Villarreal Club de Fútbol, S.A.D. (Valencian: Vila-real Club de Futbol, S.A.D.), usually abbreviated to Villarreal CF or just Villarreal, is a Spanish football club based in Vila-real, a city in the province of Castellón within the Valencian Community. Founded in 1923, it plays in La Liga, holding home games at El Madrigal, with a capacity for 24.890 spectators.
The club is nicknamed El Submarí Groguet or El Submarino Amarillo (Yellow Submarine) due to its yellow home kit, and due to being a low-profile team compared to Real Madrid, Barcelona, and Valencia, whom they have challenged for trophies over the last decade. Villarreal has often been touted as an example of a small but successful club.
Villarreal CF was founded as Villarreal CD on 10 March 1923 "to promote all sports especially Soccer." The stadium was rented for 60 pesetas a month and ticket prices were set at half a peseta for men and a quarter of a peseta for children. Women were granted free admission. On 17 June 1923, Castellón, a modern rival of the club, played the first match against a club named after Cervantes. On 21 October of that year, Villarreal played their first game ever, playing against Castellón. Villarreal started off with a kit of white shirts and black shorts, reflected in their first badge.
