NBA star Karl-Anthony Towns made a political statement at the Super Bowl -- making sure everyone knew he was rooting for the Eagles ... and Meek Mill.
KAT, flanked by his smokin' hot GF, came to the big game reppin' a "Free Meek Mill" Eagles jersey -- a public sign of support for the imprisoned Philly rapper (and unofficial team rapper).
He wasn't the only one -- NFL studs Todd Gurley and Melvin Ingram also came through U.S. Bank Stadium rockin' Meek ... while LeBron shouted out the #FreeMeek movement on social media.
Of course, Towns was also PUMPED on the outcome of the game ... yelling like a maniac and proudly proclaiming, "I ain't never been so happy!"
