Harry Thumann (born 28 February 1952; died 2001) was a German electronic composer, record producer and sound engineer. He designed and built groundbreaking synthesizers and studio equipment from the early 1960s onwards.

Born Harald Thumann in Germany, he started out as a drummer while getting a thorough grounding in audio engineering in German broadcasting. When touring lost appeal, Thumann put his musical and technical experience to work and started his first recording studio in a bedroom at the family home. Thumann participated in the development of the SSL 4000 series of consoles, and took the first one for this studio. Premises for a permanent studio with live-in accommodation were found in Germering near Munich, and Countrylane Studios were born.
