The 1969–70 Idaho State Bengals men's basketball team represented Idaho State University during the 1969–70 NCAA University Division basketball season. Led by third-year head coach Dan Miller, the Bengals played their home games on campus at Reed Gym in Pocatello.

Idaho State finished the regular season at 14–11 overall, with a 11–4 record in the Big Sky Conference, runner-up to champion Weber State.

Junior guard Willie Humes averaged nearly 29 points per game and was unanimously selected to the all-conference team; junior guard O'Neill Simmons was on the second team.

The new ISU Minidome was completed after the season and became the new home court that autumn.
