Oakland Coliseum, branded as RingCentral Coliseum for naming rights reasons, is a multi-purpose stadium in Oakland, California. It is located on 7000 Coliseum Way, adjacent to the Oakland Arena (formerly Oracle Arena) along Interstate 880. It is the home field of the Oakland Athletics of Major League Baseball; as of 2017, its playing surface has been dedicated as Rickey Henderson Field, in honor of Hall of Famer and former Athletics left fielder Rickey Henderson.

It was formerly the home of the Oakland Raiders of the National Football League from 1966 until 1981 (when the team moved to Los Angeles), and again from 1995 until 2019 (when the team moved to Las Vegas), which made it the last remaining stadium in the United States shared by professional baseball and football teams. It has also occasionally been used for soccer, including hosting selected San Jose Earthquakes matches in 2008 and 2009, and during the 2009 CONCACAF Gold Cup.

The Coliseum has a seating capacity of up to 63,132 depending on its configuration; an upper deck dubbed "Mount Davis" by fans was added as part of a 1996 renovation for the Raiders' return to Oakland. In 2006, citing a desire to provide a more "intimate" environment, the Athletics blocked off the entirety of the Coliseum's third deck during its games, which artificially limited its capacity to 34,077 (making it the smallest stadium in Major League Baseball). In 2013, the Raiders also began to restrict their use of Mount Davis due to the NFL's blackout rules, reducing football capacity by around 11,000. In 2017 under new ownership, the Athletics began to reopen some of the sections in the third deck, and open the Mount Davis deck for selected marquee games.

While an NFL venue, the stadium was the second-smallest NFL stadium, larger only than Dignity Health Sports Park, the former temporary home of the Los Angeles Chargers.
