The 2020 Campeonato Brasileiro Série D was a football competition held in Brazil, equivalent to the fourth division. The competition was originally scheduled to begin on 3 May and end on 22 November, however due to the COVID-19 pandemic the tournament was rescheduled for 6 September 2020 – 6 February 2021.
Sixty-eight teams competed in the tournament. Sixty-four teams qualified from their state leagues and cups, and four relegated from the 2019 Campeonato Brasileiro Série C (ABC, Atlético Acreano, Globo and Luverdense). Luverdense declined to participate being replaced by Sinop.
The match Guarany de Sobral v Salgueiro, scheduled for 20 September 2020 (Group A3 1st round), was postponed after 12 Guarany de Sobral players tested positive for COVID-19.
In the Group A8 12th round, (14 November 2020), São Caetano players refused to play their away match against Marcílio Dias in protest over unpaid wages. Marcílio Dias was awarded a 3–0 win by forfeit.
Altos, Floresta, Mirassol, and Novorizontino qualified for the semi-finals and were promoted to the 2021 Campeonato Brasileiro Série C.
In the finals, Mirassol defeated Floresta 2–0 on aggregate to win their first title.
