Joanna Brouk (February 20, 1949 - April 28, 2017) was an American musician and composer who was active in the late 1970s and early 1980s.

Brouk grew up in St. Louis, Missouri.

She received a B.A. in Creative Writing and Electronic Music from the University of California, Berkeley. She went on to receive an M.A. in Electronic Music from Mills College. While at Mills, Brouk studied under Robert Ashley and Terry Riley.

Brouk self-released a number of recordings on cassette via her own label, Hummingbird Productions.

Brouk's first release, Healing Music, featured the flute of American composer Maggi Payne. Her 1981 recording, Sounds of the Sea, included field recordings of nature sounds, vocals, and manipulated electronic and acoustic instruments. Brouk's music was known in New Age Music circles but did not receive a great deal of mainstream recognition.

In 2016, a collection of archival recordings and selections from cassette releases, Hearing Music, was released by The Numero Group.

In 1985, Brouk stopped composing and recording music after moving to San Diego, California, where she married and gave birth to a son, and took up the practice of transcendental meditation.
