The 2019–20 Campeonato de Portugal was the seventh season of Portuguese football's renovated third-tier league, since the merging of the Segunda Divisão and Terceira Divisão in 2013, and the fifth season under the current Campeonato de Portugal title.
A total of 72 teams competed in this league, which began in August 2019 and was scheduled to finish in June 2020.
On 8 April 2020, the Portuguese Football Federation (FPF) cancelled all non-professional competitions due to the COVID-19 pandemic in Portugal.
The following month, on 2 May, the FPF ruled that Vizela and Arouca, the two teams with the most points in all first-stage series at the time of cancellation, were promoted to the 2020–21 LigaPro.
No league winner title was awarded and no teams were relegated to the District championships.
