Sociedad Deportiva Ponferradina, S.A.D. is a Spanish football team based in Ponferrada, in the El Bierzo region, in the autonomous community of Castile and Leon. Founded on 7 June 1922 it plays in Segunda Division, holding home matches at the Estadio El Toralin, a soccer-specific stadium with a seating capacity of 8,400 spectators.
The team's kit consists of a blue and white striped shirt, and blue shorts.
Sociedad Deportiva Ponferradina was founded in 1922. The first idea of the executive committee to arrange a stadium was to build it inside the castle of Ponferrada, which was eight centuries old. King Alfonso XIII denied the building permit, which led to the construction of Santa Marta; the opening match was played 8 September 1923, a friendly against Cultural y Deportiva Leonesa.
Ponferradina spent the vast majority of its professional years in the fourth and third divisions. In 1967, with the club in the former category, it achieved an historic 6–1 win against La Liga giants Real Madrid.
