José Ramón Calderón Ramos (born 26 May 1951 in Palencia, Spain) is a lawyer and an ex-President of Spanish sports club Real Madrid.

Calderon was elected President of Real Madrid in 2 July 2006, winning the elections with 8,344 votes whilst Juan Palacios was second with 8,098. After discussions with his football director, Predrag Mijatovic, Calderon hired Fabio Capello as club manager, after initially considering Bernd Schuster, the manager of Getafe.

Amongst his promises when running for election was the signing of Arjen Robben from Chelsea, Cesc Fàbregas from Arsenal and Kaká from AC Milan. Calderón fended off allegations of making illegal approach from the clubs in question. He was only successful with Robben.

On 19 July 2006 he announced his first two signings, Fabio Cannavaro and Emerson; both signed from newly demoted Juventus for an estimated €20 million.

He later signed Ruud van Nistelrooy from Manchester United and Mahamadou Diarra from Olympique Lyon as well as delivering on his promise to acquire Arjen Robben from Chelsea. A year long loan swap deal was also concluded with José Antonio Reyes from Arsenal moving to Real Madrid in exchange for Júlio Baptista. Before the start of the 2008/2009 season, he tried to deliver Cristiano Ronaldo to the club, however failed in this ambition. Due to his re-election bid he was eager to promise securement of Ronaldo. This had been a common strategy to promise big names during re-election.
