I've always thought she was the strongest, but then I hear people telling me that Power Girl and Supergirl have the same super strength as Diana. Is she the strongest?

If you factor in all categories like speed, durability, fighting skill, reaction speed, strength, and experience, i think she is the strongest.

" @AQD:  i was under the impression powergril was the strongest "

Yes she is.

Tough call. If not her, then it's most definitely Power Girl.

Barda, Maxima, power girl all may be stronger.

" If you factor in all categories like speed, durability, fighting skill, reaction speed, strength, and experience, i think she is the strongest. "

Wonder Woman is the most powerful female hero on Earth. But I think it's been said that Supergirl will become stronger than her in the future. If that's true you have to think Power Girl will be physically stronger as well.  

"If that's true you have to think Power Girl will be physically stronger as well.   "

" @AtPhantom: Yeah I think you really do. "

No you don't. You would if there was any pattern and relation between them. There isn't. There's the same race from completely different universes. There is nothing about the one that is necessarily true about the other. "

"What? they are the same person from alternate Earth's. I think that's a pretty strong relation between the two. "

Well, it's not. One version of the character does not have to share the powers of another version. This is evident in DCU time and time again. "

It's a toss up between PG and WW; they've fought before and WW was able to subdue her but I don't think it was a definitive whose stronger. I do think both characters lose merits to their names "POWER GIRL and WONDER WOMAN" when they get matched up against someone and fight to a stalemate

"Yeah but in this case they do. Their power sets are exactly the same. As I understand it Kryptonian's get more powerful the longer they are near a yellow sun. I can see no reason why this should apply for Supergirl but not Power Girl. "

Power Girl and Wonder Woman have fought. Power Girl hit Wonder Woman hard enough to send to flying into another country. The rest of the fight was basically just a back and forth. They seemed pretty equal actually. She was also strong enough to lift a crashing spaceship that was described as large enough to destroy Manhattan. I'm not sure exactly how big that would be, but it made her looks like an ant in comparison.

They have all been written differently.

In my opinion though...it's always Diana.

Well let's see.

In SG #1 Kara herself states that Karen is indeed STRONGER

Batman backs Kara's merit up by saying she may be on par with superman

Wonder Woman vs Superman

PG vs Blue moon who states she is stronger than SM 

The bullets that bounce off PG; hurt WW

PG lives up to the family moniker of being faster than a speeding bullet.

Now i do think, Wonder Woman is the strongest Female in the DCU; but PG's attacks are so much more versitle than that of Diana. If these Two fought Three times, I'd give Diana two wins though.

Let's just go through this a bit.

While Power girl and Supergirl are both powerful, I think Kara is the stronger of the two.  She's been able to subdue PG more than once, and it's been stated the Kara might be more powerful than Superman because she metabolizes yellow sunlight at a higher rate.  Going off the fact that PG isn't as strong as superman, I'd say this makes Kara the stronger of the two of them.  This might even make Kara stronger than WW.  However, despite the fact that Kara may be stronger, I still think WW is the most powerful if we're including speed, stamina, battle training and knowledge, etc.

Hmm, Id say that Wonder Woman is the strongest.  As for number two, Id have to give it to Power Girl, seeing as how she is fully developed and Supergirl is still a teenager.  Yes its been said that Kara might be stronger than Superman, but it only seems that way because Superman said that he's had to hold back in order to avoid killing people, he's been doing it so long its become a reflex, where Kara has been running at full tilt from the get-go.

The answer is yes.

I don't think she's the absolute most powerful, but she's one of the strongest females in DC.

" It's a toss up between PG and WW; they've fought before and WW was able to subdue her but I don't think it was a definitive whose stronger. I do think both characters lose merits to their names "POWER GIRL and WONDER WOMAN" when they get matched up against someone and fight to a stalemate "

I think you run into the issue of the Kryptonian vs. magic issue in this question. For pretty self-evident storytelling reasons, they don't want to limit the powers (and subsequently the possibilities) for characters too specifically. You always want to show your characters heroically struggling and all that.

However, even if PG were at like All-Star Superman levels of yellow sun radiation, I think there would be a way for Diana to magically defeat her. While PG might have the potential to be physically stronger than Diana in some cases, I think Wonder Woman is (and should be) the strongest DC woman if not all around person. I am partial to the idea of her being a queenly/mother figure to the whole DCU though =)

OK, let's recap...  Some people say WW is more powerful than PG and SG, others believe SG is stronger than both because she's still growing (no pun intended), and other think PG is stronger.

Fact #1:  WW is as strong as Hercules if not a bit stronger, and a mistress of warfare and combat.  She has over 2 decades of combat training under her belt, err... girdle.  Superman has been shown capable to defeat Herc and Diana in single combat.  It is only because he was once mind-controlled in Superman: Sacrifice that Diana got the upper hand against him. 
Fact #2: SG is still growing in her strength and powers, and has not been truly tested in combat techniques, even though she has been taught by Amazons for a short time!  As a Kryptonian, her power levels are expected to grow up to Superman Class levels when she's older.  Plus, she's not inclined to hold back being an angst ridden teenager, so she's pretty much demonstrated all that she is right now.
Fact #3: PG is from an alternate universe (Earth-2) whose power levels were almost as vast as Kal-L , however, due to the Crisis on Infinite Earths, her power levels were decreased to far less than Pre-Crisis strength, but still is Kryptonian, and therefore stronger than WW.  And it was stated that Earth-2 Superman was stronger than Kal-El during Infinite Crisis, ergo, Power Girl should be stronger than Supergirl.  Her fighting techniques are not greater than WW, which I term PG's style as bar brawling/scrapping.  That would give WW a distinct advantage.  Being able to lift greater weights doesn't mean you can inflict the most damage.  ADVANTAGE to WW for a fight, but not in strength.

So, recap from this...  Supergirl and Power Girl's strength should eventually cap out sometime, but WW is already at her peak.  Hate to say it, but PG's the strongest.

My two cents... Jim

Supergirl is stated to be as strong as Superman when he is holding back. Kara has no experience with her powers and never holds back. That's why she appears so powerful. Superman spent his whole life holding back his powers to fit in, to feel normal.

I don't know why there is a comparison between Wonder Woman and Power Girl.If you compare their feats Wonder Woman is obviously stronger.There is nothing to debate.

She,Power Girl or Big Barda

The way I have looked at it is in terms of raw physical power, then Power Girl and Supergirl are easily the strongest, the Kryptonian heritage and all. Now what sets Wonder Woman apart is her fighting skill combined with her own natural abilities, which are still
quite powerful. In a knock down drag out brawl I think Wonder Woman would emerge the winner.

Wonderwoman is in the top 5 I think:  
 
People that are stronger than her Physically:  
 
Number 1: She is "Too Strong, She's TOO STRONG BY MILES" 
 

 
  
 
Number 2: Blue Moon: 
 
As strong as superman:

Powergirl: 
 
Overpowered Wonderwoman in their fight, and Wonderwoman says "She is AT LEAST as strong and as fast as I am" 
 
  

 
 
 
 
 
I think Wonderwoman is very close to powergirl so she is roughly 4th in strength. 
 
But is number 1 overall due to her unrivalled skill. She is able to beat those who are Physically stronger than her.

I got the following from the DC / Wikia database...  http://dc.wikia.com/wiki/Wonder_Woman_%28Diana_Prince%29
 
Superhuman Strength: Granted by Demeter (Goddess of the Earth). Diana is literally as strong as the Earth because of her link to the planet granted to her by Demeter. She is said to be 'stronger than Hercules'. It is obvious her strength is magical in nature, given her height and weight. Wonder Woman is known to be one of the strongest beings in the DCU, generally shown to be nearly in the same class as Superman himself and to physically over-match other beings such as Supergirl without too much effort. She is considered to be the strongest superheroine in the world. After Superman, she is the strongest superhero in the DCU.  She has godlike strength and also invulnerability due to her aegis-made shield magic bracelets. With her superhuman strength and superior fighting abilities, she has proven to be able to take on any other member of the Justice League in combat. In the events of Justice League: League of One, she was able to defeat even the other six main members through a combination of planning and power in order to save their lives and the world. She is strong enough to lift weights well into the megaton range and even pull 1/3 of the earth.
 
The same database does say that Power Girl has strength on a PAR with Super Man:
 
Superhuman Strength: Her physical strength appears to be on a par with that of Superman and Supergirl. Her powers can be suppressed by red solar radiation. It has been implied, though not yet specifically shown, that like Superman, she can sun-dip and supercharge her powers. 
 
But "on a par with Super-Man" doesn't necessarily mean EQUAL to that of Super-Man...
 
So, it seems fairly straightforward here...  Diana is the strongest Female in the DC universe, but Power Girl and Super Girl have to be pretty darn close to her strength level...

@Timandm:  
 
Wikipedia is wrong because Wonderwoman has stated that she was weaker than somebody by miles in strength. She also stated that she is almost equal to Powergirl, implying that Powergirl was stronger, and also Blue moon is equal to superman in strength, Wonderwoman admits superman is stronger than her, so it is straight forward, Wonderwoman is not the strongest. 

 
 
She is "Too Strong, She's TOO STRONG BY MILES" 

How can Wonderwoman be the strongest. 
 
Blue moon is as strong as superman:

If Powergirl is at the very least equal to wonderwoman in strength and speed, how is wonderwoman stronger?

@SecretKnight: 

 Wonderwoman being in the trinity is nothing to do with her strength, it is mostly that she is the major superheroine of DC

 
But to both of you, Wonderwoman Beats ANY woman the majority of the time, because of her SKILL, E.g. I prefer powergirl as I like kryptonians, but Powergirl was easily restrained using skill and so was Supergirl. 
 

 
 
See she may not have made PG bleed, as PG did to her, but she is still the boss. She was able to use her BRAIN, and restrain her to get PG to come to her senses. 
 
So WW is the best at her job, even if she is only 3rd out of an infinite number of women in DC  ; - )

NO, it's Maxima you noobs!
 
that bitch beat up both Orion and Doomsday like little babies, and temperarly made superman her sex-slave.
 

I don't think most of the scans of PG fighting WW can be used as actual evidence based on two important reasons. 
1) PG is possessed, which leads me to think that she is not in complete control of her powers and is using fighting tactics she may not normally use.  The possessor may also be pushing PG to use all her strength.  True, she hit Wondy with some cool stuff, but considering WW still subdued her means it wasn't enough. 
2) WW doesn't want to fight Karen so it's not exactly like she's trying to "win".

No,pre-crisis supergirl,or power girl.

I think Comic Vine needs to define the term STRONGER with regards to superheros. It's thrown around a lot on this sight and in most cases does not have much relevance.
Its better to think of powergirl supergirl superman etc to be in the same physical strength class and leave it at that.
 
Whoever has the most skill in battle is going to win in any kind pure combat fight. The difference in strength is negligible.
 
with regard to physical strength as in who can lift the most Wonder Woman is not the strongest.  With regard to every other kind of strength like strength of character, intellectual strength, Strength of will ETC Wonder Woman wins hands down.

she may not be the technical strongest, but she's the toughest overall IMO
