1921–22 Idaho Vandals men's basketball team

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.

The PCC became an eight-team league this year with the addition of USC and Idaho; the Vandals won the season title, and repeated the next year. They were led on the court by captain Rich Fox; "Bullet" became the head coach five years later.

At the six-team National Tournament in Indianapolis, Idaho lost 31–38 in the quarterfinal to runner-up Kalamazoo.

Idaho (16–1) was also the champion of the Northwest Conference, which was the five teams of next year's PCC Northern Division plus Whitman, Willamette, and Montana. The only loss was at Montana, on a small floor.
