Bert Lown (born Albert Charles Lown;[1] 6 June 1903 – 20 November 1962) was an American violinist, orchestra leader, and songwriter.

He began as a sideman playing the violin in Fred Hamm's band, and in the 1920s and 1930s he led a series of jazz-oriented dance bands (the most famous being the Biltmore Hotel Orchestra), making a large number of recordings in that period for Victor Records.

By the mid-1930s he quit leading the orchestras, becoming a booking agent and manager; eventually he left the music industry and moved on to executive positions in the television industry.

He died of a heart attack in 1962 in Portland, Oregon.

The song writing, Lown's collaborators included Moe Jaffe, Jack O'Brien (pianist with Ted Weems in the 1930s), and Fred Hamm.
