The Baltimore Colts were a professional American football team based in Baltimore, Maryland. The first team to bear the name Baltimore Colts, they were members of the All-America Football Conference (AAFC) from 1947–1949, and then joined the National Football League (NFL) for one season before folding. In 1953 they were replaced by a new franchise that revived the Baltimore Colts name; this team is now the Indianapolis Colts.
