The 1994 U.S. Open Cup was the 81st edition of the soccer tournament to crown the national champion of the United States.

The Greek-American A.C. of San Francisco returned to claim a second national Open Cup championship (their first being in 1985), by defeating Milwaukee's Bavarian Leinenkugel 3–0 at UGH Field in Oakford, Pennsylvania.

The Greeks then rolled to a 3–0 victory over the Philadelphia Flames in the semifinal.

Greek-American won the match behind two goals from Mike Deleray and one from Derek van Rheenen.

The victory marked the third consecutive title for a Northern California team in the Open Cup.
