1961 Major League Baseball expansion

The 1961 Major League Baseball expansion resulted in the formation of two new Major League Baseball (MLB) franchises in the American League (AL). A new club was started in Washington, D.C., and took the existing name of the Senators, as the previous team of the same name moved to Minnesota for the start of the 1961 season and became the Twins. The second new franchise was granted to an ownership group led by Gene Autry for a team in Los Angeles who named themselves the Angels. The two new teams each paid a fee of $2.1 million and became the 17th and 18th franchises in MLB.

The expansion was part of an initiative in response to the perceived threat of a proposed third major league, the Continental League. In 1962, the National League (NL) also added two new teams, the Houston Colt .45s (later renamed the Astros) and the New York Mets.
