The Indianapolis Colts are a professional American football team based in Indianapolis, Indiana. They are members of the South Division of the American Football Conference (AFC) in the National Football League (NFL).

The club was officially founded in Baltimore, Maryland in 1953, but can trace its history to the Dayton Triangles, a founding member of the NFL that was originally created in 1913. After a series of changes, it assumed the "Baltimore Colts" name, replacing a previous team that folded in 1950. Playing at Baltimore's Memorial Stadium, the Colts became the first NFL team to have cheerleaders. The team then relocated to Indianapolis in 1984, first playing at the RCA Dome before moving to Lucas Oil Stadium in 2008.

The Colts won four NFL championships (three NFL Championships in 1958, 1959, 1968; and Super Bowl V in 1970) while in Baltimore. Since moving to Indianapolis, they won Super Bowl XLI in 2007. Also since 1998, the team has become the first in league history to win 12 games or more in five consecutive seasons—extending this record to seven after the 2009 season.

The team headquarters and practice facilities are also located in Indianapolis. The club currently holds their annual training camp from late July to mid-August on the campus of Rose-Hulman Institute of Technology in Terre Haute, Indiana.
