O.co Coliseum (originally known as Oakland–Alameda County Coliseum and commonly Oakland Coliseum) is a multi-purpose stadium, located in Oakland, California, in the Coliseum Industrial area. It is the only multi-purpose stadium left to serve as a full-time home to both a Major League Baseball team (the Oakland Athletics) and a National Football League team (the Oakland Raiders) in the United States. The Coliseum was also home to the San Jose Earthquakes of Major League Soccer, who used the stadium for several games during their 2008–2009 seasons.
