U.S. Snowboarder Jamie Anderson -- I'M QUITTING TINDER ... I'm Too Hot for App Dating

U.S. Olympic snowboarder Jamie Anderson says she's officially ditching her Tinder account ... telling TMZ Sports she's way too good-looking to be hunting for dudes through an app.

Anderson -- who won gold in Sochi -- famously told the media she used Tinder to meet other sexy athletes in Olympic Village ... but now, Jamie says she's having a serious change of heart.

"I don't need it," Jamie says ... telling us the app didn't ever lead her to a quality hookup during her stint in Russia.

So, what's Jamie's plan now?
