Real Betis Balompié, S.A.D., more commonly referred to as Real Betis is a Spanish football club based in Seville, in the autonomous community of Andalusia. Founded on 12 September 1907, it plays in LaLiga, having won the Segunda División in the 2014–15 season. It holds home games at Estadio Benito Villamarín in the south of the city.

Real Betis won the league title in 1935 and the Copa del Rey in 1977 and 2005. Given the club's tumultuous history and many relegations, its motto is Viva el Betis aunque pierda! - "Long live Betis even when they lose!”.

Betis was founded in 1907, under the name of Sevilla Balompié. In 1914, the club was merged with Betis Football Club, a breakaway from Sevilla FC. From that moment onwards, the club has been known as Real Betis Balompié. The club switched to their now-famous green and white jerseys in 1920.
