Mark Cuban Says 'I Would Support' Changing NBA Logo to Kobe Bryant

Well, this is a big deal ... Dallas Mavericks owner Mark Cuban says he's on board with the movement to change the NBA logo to Kobe Bryant -- telling TMZ Sports, "I would support it."

Not only have MILLIONS of people signed a petition to have the league swap out the current logo which features an image of Jerry West, but a bunch of NBA stars have backed it as well ... from Paul Pierce to Jamal Crawford and more.

Outside of basketball, stars like Justin Bieber, Julian Edelman, Snoop, Usher, Meek Mill and more have joined the #ChangeTheLogo movement.

As for Cuban, he's already honored Kobe by retiring the #24 jersey in the Mavs organization (despite Kobe never playing for Dallas) ... and now he's down for an even bigger tribute.

"I just think it's so much more than basketball," Cuban told us ... "He brought so many people together."

Unclear exactly what it would take to get the league to make the move, but having one of the league's most influential owners get behind the push seems pretty significant to us.
