Javier García Portillo (born 30 March 1982 in Aranjuez, Community of Madrid) is a Spanish footballer who plays for UD Las Palmas as a forward.

In 1994, aged 12, Portillo entered Real Madrid's youth system. During seven seasons he was a prolific scorer, netting 150 goals and breaking a record previously held by Raúl. In 2002, he signed his first professional contract, running until 2007, with a release clause of €35 million.

On 6 October 2002, Portillo made his first main squad appearance, starting in a 5–2 home win against Deportivo Alavés, ending that season with five goals in only 10 outings. He also scored a vital last-minute equaliser against Borussia Dortmund in the UEFA Champions League second group stage, a goal which ultimately proved to be crucial in Real Madrid making it into the knockout stages.

In July 2004, Portillo was loaned to Serie A club ACF Fiorentina, but was recalled by new boss Vanderlei Luxemburgo, who arrived midway through 2004–05. However, the same coach deemed him surplus to requirements and another loan ensued, to Belgian League's Club Brugge KV.
