The 2004 Anaheim Angels season was the franchise's 44th since its inception. The regular season ended with a record of 92–70, resulting in the Angels winning their fourth American League West title, their first since 1986. Their playoff run was short, as they were quickly swept by the Boston Red Sox in the American League Division Series. The season was notable for being the last season the Angels played under the "Anaheim Angels" moniker; owner Arte Moreno changed the team name to the controversial "Los Angeles Angels of Anaheim" moniker the following season. It was also notable as the season in which newly signed outfielder Vladimir Guerrero won the AL Most Valuable Player award, the first time an Angels player had been so honored since Don Baylor in 1979.
