The 1958–59 Washington State Cougars men's basketball team represented Washington State College for the 1958–59 NCAA college basketball season. Led by first-year head coach Marv Harshman, the Cougars were members of the Pacific Coast Conference and played their home games on campus at Bohler Gymnasium in Pullman, Washington.

The Cougars were 10–16 overall in the regular season and 3–13 in conference play, tied for last in the standings.

Harshman was formerly the head coach at his alma mater, Pacific Lutheran, for thirteen seasons, and he led the Cougars for thirteen years.
