Frank G. Comstock (September 20, 1922 – May 21, 2013) was an American composer, arranger, conductor and trombonist. For television, Comstock wrote and arranged music for major situation comedies and variety shows; his theme and incidental music for Rocky and His Friends (1959–1964) are probably his best-remembered works. Additionally, his music for Adam-12 earned him a 1971 Emmy nomination.

Comstock's recording credits include eight Hi-Lo's albums and backing arrangements for major recording stars. His 1962 instrumental album, Project: Comstock - Music from Outer Space became a classic and was released on CD in 2004. Recently, Comstock wrote new big-band arrangements for Brian Setzer's Wolfgang's Big Night Out (2007) and Songs from Lonely Avenue (2009) CDs.
