"By the Light of the Silvery Moon" or "By the Light of the Silv'ry Moon" is a popular love song. The music was written by Gus Edwards, and the lyrics by Edward Madden. The song was published in 1909 and first performed on stage by Lillian Lorraine in the Ziegfeld Follies of 1909. It was one of a series of moon-related Tin Pan Alley songs of the era. The song was also used in the short-lived Broadway show Miss Innocence when it was sung by Frances Farr.

Gustave Edwards was an American composer, songwriter and film director. He also was a vaudevillian, organised his own theatre companies and was a music publisher.
