The Campeonato de Portugal was introduced in 2013 as the new third-level championship, under the name Campeonato Nacional de Seniores (Seniors National Championship), replacing both the Segunda Divisão and Terceira Divisão (former third and fourth divisions, respectively).
With the creation of the Liga 3 as the new third division from the 2021–22 season, the Campeonato de Portugal was demoted one level.
