Antonio José Puerta Pérez (26 November 1984 – 28 August 2007) was a Spanish footballer who played solely for Sevilla.

Mainly a left midfielder who could also operate as an offensive left back, he died on 28 August 2007, affected with arrhythmogenic right ventricular cardiomyopathy, three days after suffering a series of cardiac arrests during a league game against Getafe on the 25th.

Born in Seville, Andalusia, Puerta joined Sevilla FC as a boy and spent a total of 14 years at the club, growing up at the club's acclaimed youth system alongside other players such as Sergio Ramos, Jesús Navas, José Antonio Reyes, Alejandro Alfaro and Kepa Blanco. His first division debut came on 21 March 2004, as he played 71 minutes in a 0–1 home defeat against neighbours Málaga CF.

Definitely promoted to the first squad for 2005–06, Puerta became intimately connected to Sevilla's history on 27 April 2006, when he netted against FC Schalke 04 in the UEFA Cup semifinals. In the final moments of the match, he received a long ball and struck it with his left foot, for the 1–0 final (and aggregate) win. Sevilla went on to collect five titles in fifteen months, with Puerta scoring his penalty shootout attempt in the 2007 UEFA Cup final, against fellow first-divisioner RCD Espanyol. His impressive performances earned him international recognition and reported interest from Arsenal, Manchester United and Real Madrid, but all bids were rejected.
