I read somewhere that he is 26 years old.

I just have a feeling that he's around 21. Dunno why, but when I get that feeling, I know it's gotta be true...wouldn't 26 be kind of old? He's almost ten years older than Rapunzel if so XD

Yep. XD 21. I'm going with it.

I'd definatley say 21 or 22, but, If he was 22, he's definatley not been it for long :L

Apparently he was 26 years old while Rapunzel was 18. This was decided as the crew designed Flynn Rider.

Wow, really? O_o Kinda old for her you'd think.

@Puffedwarrior, haha perhaps... 8 years difference. Well! If that is too large an age difference, you can always imagine him as younger. :D

his age probably isnt specified in the film to keep him more mysterious:P

@Valerie217, true, true.

Here's a site with an answer. I don't know if this is true, but this is where I got my answer that he is 26.

8 years difference is long time, but it don't matter too much. I think age difference I probbly complain more about is if he was old as her father,then that be more to complain about.But he not so it's not too bad plus he really don't look his age anyways,which is good.I know I don't look my age either I look three to fours younger then what I actually am.I get that from alot people,they ask my age and when I tell them they say you don't look it and that I look younger,but hey I take that as complement.

His age isn't specified probably because he doesn't even know how old he is, being an orphan and all.
He seems really old, but maybe that's just because he's been exposed to the secular and evil world since ever.
But we can all agree that he's hot, right?

I have actually found out Flynn/Eugene actual age and the way i can prove it is I called Nathan Greno one of the directors of Tangled and asked him and he told me Flynn/Eugene's actual age is he's 23 years old bc since Rapunzel was 18

@12Rapunzel: WOW you RANG UP Nathan Greno awesome HAHA. Anyway thanks for the answer cause it would be weird having a teen falling for an older man who's heading 30,I kinda knew he was in his 20s. Is it just me or does Rapunzel look like someone in her 20s when she's a brunette?. Hilarious how a hair colour can make you appear older eh. Plus if you notice in Tangled Eugene has frown lines,whereas Rapunzel hasn't.

Thanks again.
