The San Francisco Fog was a Major Indoor Soccer League franchise which existed for only one season, 1980–1981.
The Fog, which played their home games at the Cow Palace, finished their single season of existence at 11–29. The team used The Eagles "Heartache Tonight" as their anthem.
On May 28, 1980, at the end of the 1979–1980 season, the owner of the Detroit Lightning, David Schoenstadt, moved his team from Detroit, Michigan to San Francisco, California where he renamed the team the San Francisco Fog. It had few decent players and drew under five thousand fans per game. After a dismal 1980–1981 season, Schoenstadt moved the franchise to Kansas City in May 1981 where the team flourished as the Kansas City Comets, the Fog finished 4th in the West division and did not qualify for the playoffs.
