Erling Wold (born January 30, 1958, in Burbank, California) is a San Francisco-based composer of opera and contemporary classical music.

His work at this time with a number of San Francisco performance artists and dancers led to his continuing interest in theater.

After leaving Yamaha in 1992, he cofounded Muscle Fish, an audio and music software company, later acquired by Audible Magic.

The success of the production led to a residency at ODC Theater in San Francisco, where he premiered his opera Queer based on William S. Burroughs' early autobiographical novel of the same name in 2001 and Sub Pontio Pilato, an historical fantasy on the death and remembrance of Pontius Pilate in 2003.

There have been few purely musical works during this period, but some notable exceptions are Close, played by Relâche and others, the piano pieces Albrechts Fluegel, premiered by Finnish pianist Marja Mutru, and Veracity.
