The 1921–22 Idaho Vandals men's basketball team represented the University of Idaho during the 1921–22 college basketball season. Members of the Pacific Coast Conference, the Vandals were led by second-year head coach Dave MacMillan and played their home games on campus at the Armory and Gymnasium in Moscow, Idaho.
The Vandals were 19–2 overall and 7–0 in conference play.[2]
The PCC became an eight-team league this year with the addition of USC and Idaho; the Vandals won the season title,[3] and repeated the next year. They were led on the court by captain Rich Fox; "Bullet" became the head coach five years later.
