Edythe A. Baker (August 25, 1899 – August 15, 1971) was an American jazz pianist.

Baker was born in poverty in Girard, Kansas to Asa and Sophronia Baker. After her mother died around 1910 she was sent to Kansas City, Missouri to live, and attended a convent. There she was trained in piano fundamentals, eventually working for a music store. After touring with a vaudeville troupe in 1918, Edythe moved to New York City in 1919. There she made piano rolls (for Aeolian and Duo-Art) between 1919 and 1926; these included ragtime and pop pieces. She worked on Broadway in musicals and performed with vaudeville troupes such as the Ziegfeld Follies.

In 1926, Baker relocated to England, and recorded twenty two pieces there between 1927 and 1933. She became a star there after appearing in revues in 1927. Constant Lambert saw her perform, and suggested to Harold Rutland that she might be the soloist for the premiere of his jazz-influenced choral piece The Rio Grande in 1930. However, Hamilton Harty was the eventual soloist.

She married into the banking family of Gerard d'Erlanger in 1928, and left the music industry after the mid 1930s. After divorcing d'Erlanger, she romanced the Duke of Kent. Baker returned to the United States in the late 1940s, at one point settling in Laguna, California and enjoying a quiet life of bridge and gardening. Little was heard of her until her death in Orange, California in 1971.

A selection of Baker's piano rolls, recorded by Dave Jasen, were reissued on an album released by Folkways Records in 1983.

Baker died in California in 1971, aged 71.
