Gayle McCormick (November 26, 1948, St. Louis, Missouri, U.S.A. – March 1, 2016, St. Louis, Missouri, U.S.A.) was an American singer best known for her work with the rock band Smith.

While a teenager, she acquired experience performing as a soprano with the St. Louis Symphony Orchestra, as a member of the Suburb Choir. She went on to join the local group Steve Cummings and the Klassmen, before moving to Los Angeles where she became a member of Smith. Spotted by Del Shannon, Smith landed a record contract with the Dunhill label resulting in their debut album A Group Called Smith (1969). Their cover single Baby It's You earned a Top 5 placing on the American Pop Charts and gold record status. They covered The Band's The Weight for the Easy Rider soundtrack in 1969, after a licensing problem with the original recording arose. From their success, they performed on the TV programs The Ed Sullivan Show and American Bandstand. Following the recording of their album Minus-Plus (1970), they disbanded. McCormick went on to a solo career and achieved a Top 50 hit with It's a Crying Shame (1971). She retired from the entertainment industry during the mid 1970s. She died following a battle with cancer.
