The 2009 NCAA men's volleyball tournament was the 40th annual tournament to determine the national champion of NCAA men's collegiate indoor volleyball. The single elimination tournament was played at Smith Fieldhouse in Provo, Utah during May 2009.^[1]

UC Irvine defeated USC in the final match, 3–2 (26–30, 30–23, 26–30, 30–17, 15–12), to win their second national title. The Anteaters (27–5) were coached by John Speraw.

UC Irvine's Ryan Ammerman was named the tournament's Most Outstanding Player. Ammerman, along with six other players, comprised the All Tournament Team.

Until the creation of the NCAA Men's Division III Volleyball Championship in 2012, there was only a single national championship for men's volleyball. As such, all NCAA men's volleyball programs, whether from Division I, Division II, or Division III, were eligible. A total of 4 teams were invited to contest this championship.
