Jesse Alexandria Stacy (August 11, 1904 – January 1, 1995) was an American jazz pianist who gained prominence during the swing era. He is perhaps best known for his years with the Benny Goodman band during the late 1930s, particularly his performance at Goodman’s Carnegie Hall concert in 1938.

Stacy was born in Bird’s Point, Missouri, United States, a small town across the Mississippi River from Cairo, Illinois. His first piano teacher was Mabel Irene Bailey, who played piano for silent movies. In 1918 Stacy moved to Cape Girardeau, Missouri. He received his only formal music training with Clyde Brandt, a professor of piano and violin at Southeast Missouri State Teachers College (Southeast Missouri State University)^[3] while sweeping at Clark’s Music Store.
