The Los Angeles Angels of Anaheim are a professional baseball team based in Anaheim, California. The Angels are a member of the Western Division of Major League Baseball's American League. The "Angels" name originates from the city that was their original home, Los Angeles. The Angels have been based in Angel Stadium of Anaheim since 1966.

An expansion franchise, the club was founded in Los Angeles in 1961. Then the Los Angeles Angels, the team was based at Los Angeles' Wrigley Field (not to be confused with Chicago's stadium of the same name). The team has gone through several name changes in their history, first changing to the California Angels in midseason 1965 to emphasize their status as the only AL team in California and in recognition of their planned move from Dodger Stadium in Los Angeles to Anaheim Stadium in Anaheim the following year. When The Walt Disney Company took control in 1997, it extensively renovated Angel Stadium on the condition that both the stadium's name and the team's name contain the word "Anaheim." Disney was hoping to capitalize on the proximity of nearby Disneyland to enhance the tourism in the area, and thus the team became the Anaheim Angels.

In 2005, new owner Arte Moreno wanted to include "Los Angeles" in the team's name, in order to better tap into the Los Angeles media market, the second largest in the country. In compliance with the terms of its lease with the city of Anaheim, which required "Anaheim" be a part of the team's name, the team was renamed to Los Angeles Angels of Anaheim. Hotly disputed when initially announced, the change was eventually upheld in court and the city dropped the suit in 2009, though the team usually refers to itself as simply the Angels in its home media market.
