Gregorio Jesús Gil y Gil (12 March 1933 – 14 May 2004) was a Spanish businessman and politician. He served as Mayor of Marbella between 1991 and 2002, and presided for a 16-year tenure as president of the football club Atlético de Madrid. The Marbella city council had to be dissolved soon after his death, a legal but unprecedented movement in Spanish politics, to put an end to extreme corruption and dealings with international mafias, among other crimes.
