1964 NAIA World Series

The 1964 NAIA World Series was the eighth annual tournament hosted by the National Association of Intercollegiate Athletics to determine the national champion of baseball among its member colleges and universities in the United States and Canada.

The tournament was played at Phil Welch Stadium in St. Joseph, Missouri.

West Liberty State (27-7) defeated Grambling (24-5) in the championship series, 6–4 and 3–2, to win the Hilltoppers' first NAIA World Series. West Liberty State, who lost its first game of the tournament, won six consecutive games out of the consolation bracket to claim the title.

West Liberty State pitcher Frank Ujcich was named tournament MVP.

Prior to the Mayville State and West Liberty State game, it was discovered that Mayville State's catcher Dave Pavlesic had signed a professional contract in 1961 with the Newton-Conover Twins of the Class D Western Carolina League. As a result, Mayville State was disqualified from the tournament and had to forfeit all tournament games with their opponents being awarded 9–0 victories.
