There have been five motor racing drivers from Portugal who have participated in a Grand Prix event of the Formula One World Championship, three of which have started in a race. The first to be officially listed as an entrant was Casimiro de Oliveira at the 1958 Portuguese Grand Prix, though Mário de Araújo Cabral was the first driver to take part in a Formula One race, doing so at the 1959 Portuguese Grand Prix. Following Araújo Cabral's final Grand Prix appearance in 1964, no Portuguese driver entered the World Championship until Pedro Chaves in 1991, or competed in a race until Pedro Lamy in 1993. Tiago Monteiro, who contested 37 Grands Prix across the 2005 and 2006 seasons, remains the country's most recent Formula One driver.
