Dave "Baby" Cortez (born David Cortez Clowney on August 13, 1938 in Detroit, Michigan) is an American pop music and R&B pianist and organist.

Clowney made his first record in 1956 under his own name but it was not until three years later when he scored a major success using the stage name Dave "Baby" Cortez. His instrumental, "The Happy Organ" was the first pop/rock hit to feature the organ as lead instrument. The 45rpm single went to No. 1 on Billboard magazine's Hot 100 charts. More than forty-five years later, the record is still frequently played on the radio and a favorite "download" on the Internet.

Cortez had another Top Ten hit in 1962 with "Rinky Dink".
