1977–78 Boise State Broncos men's basketball team

The 1977–78 Boise State Broncos men's basketball team represented Boise State University during the 1977–78 NCAA Division I men's basketball season. The Broncos were led by fifth-year head coach Bus Connor and played their home games on campus at Bronco Gymnasium in Boise, Idaho.

They finished the regular season at 13–13 overall, with a 8–6 record in the Big Sky Conference, fourth in the standings. In the four-team conference tournament at Missoula, the Broncos met host and regular season champion Montana in the semifinals, and lost by nine points.

Senior guard Steve Connor was named to the all-conference team; forwards Trent Johnson and Danny Jones were on the second team. The next Bronco on the first team was Vince Hinchen in 1984.

Boise State did not return to the conference tournament until 1984, when it expanded to include all eight teams.
