FFK reached the Norwegian Cup final for the first time in 1932. The semifinal against Mjøndalen was played at home in front of a record 9,000 spectators, and FFK won the match 3–0. Fredrikstad met Ørn Horten in the final, winning 6–1, and were thus Norwegian Champions. This signalled the start of Fredrikstad's first successful era, in which the club claimed four more cup titles before the start of World War II. FFK became the first club to win the new nationwide league, in 1937–38, and they won The Double the following season.
