Bad news, groupies -- Chandler Parsons says he's officially "a one-woman man" ... ending a truly epic run for the NBA's #1 stud.
But Chandler ain't gonna deny he was killin' the game earlier in his career, telling TMZ Sports, "I had a hell of a run."
We got Parsons up in the Bev Hills ... and asked him what it felt like to be the league's hottest bro -- having shacked up with celebs like Bella Thorne, Arianny Celeste, Toni Garrn and (maybe) Hailey Baldwin.
You could tell Chandler was down with it, but the Grizzlies star was quick to tell us he's only got love for smokin' hot model GF, Cassie Amato, these days.
Yeah, we know it's easy for any hooper to end up like Tristan Thompson ... but these pics make us wanna believe.
Stay strong, Chan-Dog.
