1979–80 Boise State Broncos men's basketball team

The 1979–80 Boise State Broncos men's basketball team represented Boise State University during the 1979–80 NCAA Division I men's basketball season. The Broncos were led by seventh-year head coach Bus Connor and played their home games on campus at Bronco Gymnasium in Boise, Idaho.

They finished the regular season at 10–16 overall, with a 4–10 record in the Big Sky Conference, last in the standings. BSU defeated rival Idaho in overtime in the Kibbie Dome on January 12; it was the Vandals' only home loss of the season and their last at home for over three years.

Connor announced his resignation, effective at the end of the season, with five games remaining. The Broncos lost four straight, then defeated Nevada in the finale on February 23 at Boise. Dave Leach, an assistant at Oregon State under Ralph Miller, became head coach in mid-March.

No Broncos were named to the all-conference team; center Dave Richardson and guard Dave Williams were honorable mention.
