Manus John Fish (May 1, 1892 – June 29, 1971) was an American football and baseball coach. He served as the head coach of the Newark Tornadoes of the National Football League (NFL) in 1930. In 1930, the Tornadoes moved to Newark from Orange, New Jersey. The team then hired Fish and Andy Salata to serve as co-coaches. Neither man had ever coached in the NFL before. Under the two coaches the Tornadoes were 1–11, finishing last in the league.
