Roberto Rojas González (born 17 November 1974 in Madrid) is a Spanish retired footballer who played as a right back.
Rojas graduated from Real Madrid's youth academy, and played in five matches with the first team during the 1998–99 season.
His La Liga debut occurred on 14 November 1998, coming on as a substitute for Christian Panucci at the hour-mark of an eventual 1–2 home loss against Celta de Vigo.
He appeared in 32 games in his first year, helping the Andalusians retain their recently acquired top flight status, and went on to feature for the side that conquered the 2002 UEFA Intertoto Cup, but only played in 20 league matches in his last two campaigns combined.
Rojas returned to Real Madrid in 2009, being appointed assistant manager in the Infantil A team.
