"Avalon" is a 1920 popular song written by Al Jolson, Buddy DeSylva and Vincent Rose referencing Avalon, California. It was introduced by Jolson and interpolated in the musicals Sinbad and Bombo. Jolson's recording rose to number two on the charts in 1921. The song was possibly written by Rose, but Jolson's popularity as a performer allowed him to claim composer co-credit. Originally, only Rose and Jolson were credited, and DeSylva's name was added later.

Al Jolson was a Lithuanian-born American singer, actor, and vaudevillian.
