The Castelló Masters was a European Tour golf tournament that was played annually from 2008 through 2011.

The event was held at the Club de Campo del Mediterráneo in Castellón, Spain.

The inaugural event was won by Sergio García, who also happened to be the tournament host, having grown up playing golf on the course where his father is the club professional.

In 2010, 17-year-old Italian Matteo Manassero became the youngest-ever winner on the European Tour when he triumphed by 4 strokes over Ignacio Garrido.
