Justin Bieber -- Campaigning for NBA Player to Make All-Star Team

Justin Bieber is hoping his 60 MILLION twitter followers can make a dent in NBA All-Star voting ... and he's putting his weight behind a guy who plays in Canada.

Bieber is pushing for Kyle Lowry -- a point guard for the Toronto Raptors who's having a pretty good season ... and is currently 3rd in the All-Star voting behind John Wall and Dwyane Wade.

The Canadian pop star tweeted, "Toronto has been killin it and @Klow7 deserves to be an nba all star. Make sure to vote for him. #WeTheNorth. Good luck buddy."

The All-Star game "starters" are chosen based on fan voting -- so if Bieber can mobilize his army, there's a good chance Lowry can leapfrog the other two guys in the Eastern Conference backcourt.
