Sport Lisboa e Benfica (Portuguese pronunciation: [spɔɾ liʒˈboɐ i bɐ̃ȷ̃ˈfikɐ]), commonly known as Benfica, is a sports club based in Lisbon, Portugal. It is best known for its professional football team, who play in the Primeira Liga, the top flight of Portuguese football. Currently, Benfica are back-to-back Portuguese champions.
Founded in 1904 by a group of people led by Cosme Damião, Benfica is one of the "Big Three" clubs in Portugal that have never been relegated from the Primeira Liga – the other two are rivals FC Porto and Sporting CP. The team is nicknamed Águias (Eagles) for the symbol atop the club's crest, and Encarnados (Reds) for the shirt colour. Since 2003, their home ground has been the Estádio da Luz, which replaced the original one. Benfica is the most supported Portuguese club and the European club with the biggest percentage of supporters in its own country, having more than 156,000 paying members. The club's official anthem, "Ser Benfiquista", refers to its supporters who are called Benfiquistas. Benfica is honoured in three Portuguese Orders: those of Christ, of Merit and of Prince Henry.
