American soccer clubs in international competitions

This is a list of American soccer clubs in international competitions. American clubs have participated in competitive international soccer competitions since 1963, when New York Hungaria entered the 1963 CONCACAF Champions' Cup.

Unlike other major professional sports leagues in the United States, the winners of Major League Soccer and National Women's Soccer League are not universally considered to be world champions in their respective sport. Yearly, MLS and NWSL teams will compete against other soccer clubs abroad in competitions to determine the champions of North America, the Americas, and the world.

Since 1963, American men's soccer clubs have won three CONCACAF Champions' Cup/Champions League titles, and finished runners-up five times. Starting in 2024 Women's clubs competed in the CONCACAF W Champions Cup.
