Malcolm Butler -- I GOT MY FREE TRUCK ... Thanks Chevy!

Super Bowl hero Malcolm Butler is riding high right now ... 'cause the dude just got himself a brand new FREE TRUCK ... and it's all thanks to Tom Brady.

Of course, Brady got a Chevy Colorado for being named MVP of the Super Bowl -- but said he wanted to give it to Butler ... who made the game-saving interception.

Well, Chevy heard Brady loud and clear ... and instead of letting Tom part ways with his prize, they decided to hook Butler up too ... and Tuesday in Massachusetts, Butler finally got his ride!!

"I am ecstatic that Chevrolet has chosen to reward me with a Colorado. It is just another unreal event in what has been an incredible week."

Still no word on what Brady plans to do with his truck.
