The third round of the 2021 Formula 1 World Championship is the Portuguese Grand Prix, to be held at the Portimao circuit situated just outside the biggest city in the west of the Algarve.

In 2020 the Portuguese Grand Prix, with Lewis Hamilton winning, came back to the F1 calendar for the first time after 14 years. Back in 1996, Damon Hill won at Estoril, a track that hosted Formula 1 13 times from 1984 to 1996. There were two editions of this race held in Porto in 1958 and 1960 and one in Monsanto in 1959. Alain Prost and Nigel Mansell share the record for the most Portuguese wins with three apiece.

The Portuguese Formula 1 Grand Prix takes place from 30 April to 2 May 2021.
