The 1990 NCAA Men's Volleyball Tournament was the 21st annual tournament to determine the national champion of NCAA men's collegiate volleyball. The tournament was played at the Patriot Center in Fairfax, Virginia during May 1990.
USC defeated Long Beach State in the final match, 3–1 (15–10, 12–15, 15–4, 15–6), to win their fourth national title. The Trojans (26–7) were coached by Jim McLaughlin.
USC's Bryan Ivie was named the tournament's Most Outstanding Player. Ivie, along with five 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.
