1926–27 Idaho Vandals men's basketball team

The 1926–27 Idaho Vandals men's basketball team represented the University of Idaho during the 1926–27 NCAA college basketball season. Members of the Pacific Coast Conference, the Vandals were led by seventh-year head coach Dave MacMillan and played their home games on campus at the Armory and Gymnasium in Moscow, Idaho.

The Vandals were 24–7 overall and 7–3 in conference play.

After the season, MacMillan departed for Minnesota of the Big Ten Conference, and was succeeded by alumnus Rich Fox, who coached Pocatello High School to the state title in 1927 (over Moscow in Moscow) and led the Vandals for nine seasons.

This was the penultimate season for varsity basketball at the Armory and Gymnasium as the Memorial Gymnasium opened in November 1928. The older building became the women's gym, and continues today as Art and Architecture South.
