The Campeonato de Portugal was contested as a knockout competition from 1921–22 to 1937–38. Its winners were the Portuguese national champions of the period. It was the direct predecessor of the Taça de Portugal, but its 17 titles are not retrospectively counted as Taça de Portugal wins or modern league championships. The FPF describes the later Taça trophy as an adapted form derived from this competition's challenge trophy.
