Arturo Alvarez (born June 28, 1985 in Houston, Texas) is an American soccer player who currently plays for San Jose Earthquakes in Major League Soccer.

Alvarez did not play college soccer; instead, he joined the league in 2003, signing a Project-40 contract, and was selected 13th overall in the 2003 MLS SuperDraft by the San Jose Earthquakes. In his first year, Alvarez scored his first MLS goal on June 14, 2003 vs Dallas but would go on to get limited playing time, only registering 655 minutes, and had difficulty earning playing time in 2004. However, the Quakes traded him to FC Dallas before the 2005 season in a large deal that included Richard Mulrooney and Brad Davis.

During the 2007 MLS Cup Playoffs, in the second leg of FC Dallas' Conference semifinal match with the Houston Dynamo, Alvarez was sent off for "violent conduct" after he kneed Brad Davis in the groin while out of bounds in the 47th minute. FC Dallas went on to lose the game 4–1, and the match 4–2 on aggregate.
