The 1923 San Francisco Seals season was the 21st season in the history of the San Francisco Seals baseball team. The 1923 team won the Pacific Coast League (PCL) pennant with a 124–77 record.

Dots Miller began the season as the team's manager. However, he developed tuberculosis and resigned his position in July to seek treatment at a sanitarium in Saranac Lake, New York.^[1] He died there in September 1923.^[2]
