António Maria de Mello Breyner Félix da Costa (born 31 August 1991) is a Portuguese professional racing driver, and BMW Motorsport works driver.
He is perhaps best known for winning the Macau Grand Prix invitational Formula Three race in 2012 and 2016, as well as the Formula Renault 2.0 Northern European Cup in 2009. He is the younger half-brother of Duarte Félix da Costa, also a racing driver, who primarily competes in sportscar racing.
After progressing through various levels of the junior formulae motorsport ladder, Félix da Costa's breakthrough year came during the 2012 season. Having started the season driving for the Carlin team in the GP3 Series, Félix da Costa was selected to join the Red Bull Junior Team, replacing Formula Renault 3.5 Series driver Lewis Williamson, who had failed to score a point in the first three meetings of the season. Félix da Costa assumed Williamson's drive with the Arden Caterham team, where he ultimately won four of the final five races to be held in the campaign en route to fourth position in the final championship standings, just 23 points behind eventual champion Robin Frijns. Félix da Costa moved to the Arden Caterham team full-time for the 2013 season.
