The San Diego Chargers are a professional football team based in San Diego, California.

The Chargers play their home games at Qualcomm Stadium. The Chargers continue to be the only NFL team based in Southern California, with no teams in Los Angeles since 1994.

The Chargers are the only team to start a season 0–4 and make the playoffs (1992), and the only team to start a season 4–8 and make the playoffs (2008).

Since the 2004 NFL season, they are also one of only three teams in the NFL to not have a losing record (New England and Pittsburgh are the other two), but the only one of the three that has failed to win the Super Bowl; the other two have won at least one Super Bowl title.
