The Idaho Vandals men's basketball team represents the University of Idaho, located in Moscow, Idaho, in NCAA Division I basketball competition. They currently compete in the Big Sky Conference. The Vandals are currently coached by Don Verlin and play their home games on campus at the Cowan Spectrum at the Kibbie Dome; the Memorial Gym is the alternate venue. The university is preparing to build the new Idaho Central Credit Union Arena; when the 4,200-seat venue opens in 2021, the men's basketball team, as well as the women's basketball and volleyball teams, will move to the new facility.
The program's two most notable seasons were in 1962–63 and 1981–82. The Vandals went 20–6 in 1963 and featured future hall of famer Gus Johnson. The 1982 team was ranked sixth in both polls at the end of the regular season, repeated as regular season and conference tournament champions, and reached the Sweet Sixteen of the NCAA tournament.
