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.

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.
