Real Valladolid Club de Fútbol, S.A.D., or simply Real Valladolid or Valladolid, is a football club based in Valladolid (Castile and León, Spain) from where the nickname Pucela is derived. The colours that identify the club are the violet and white, used in the form of streaks in his uniform holder from its foundation on 20 June 1928. It plays in La Liga, holding home games at the Estadio José Zorrilla, which seats 27,846 spectators.

Valladolid’s honours include a single trophy of great relevance, the defunct Copa de la Liga 1983/84. It has been runner-up in the Copa del Rey on two occasions (1949/50 and 1988/89), and has participated in two editions of the UEFA Cup (1984/85 and 1997/98) and also one edition of the UEFA Cup Winners’ Cup (1989/90). The team subsidiary, the Real Valladolid B, currently play in the Segunda División B.

Since the Club made its La Liga debut in the 1948-49 season (in which it became the first club from Castile and Leon to play in La Liga), Valladolid is the most successful football club in Castile and León by honours and history, with a total of 44 seasons in the First Division, 35 in the Second and 10 in the Third. Historically, Valladolid is the 13th best team in Spain by overall points. Valladolid is one of four clubs in La Liga in clubs with 40 or more seasons. Two of its players have risen with the Pichichi Trophy: Manuel Badenes and Jorge da Silva; and ten were internationals with the Spain national football team.

On 3 September 2018, it was announced Brazilian former international footballer Ronaldo Nazario had become the majority shareholder after purchasing a 51% controlling stake in the club.

As of 2019, Valladolid is one of six former La Liga Clubs from Castile and Leon to have been played in the Spanish top division.
