Jeri Sullavan, born Leona McGinty in 1919 in Jersey City, New Jersey, was an American singer who gained prominence through her performances on radio and in personal appearances. She moved to Bremerton, Washington, during her teenage years, where she graduated from Bremerton High School in 1936. Initially trained as a dancer, Sullavan shifted her focus to singing and took vocal lessons in Seattle, California, and Chicago.

Her career began with a modest singing job in a Bremerton ballroom, earning $1.50 per night. She soon joined Peri Maurer's orchestra as Jeri Powell and later performed with several notable orchestras, including those led by Bernie Cummins, Art Jarrett, Claude Thornhill, and Glen Gray. Sullavan's radio career took off at WSM in Nashville, leading to her becoming a regular singer on CBS, where she eventually had her own program.

During World War II, she entertained American military personnel and was recognized for her frequent performances at the Maritime Naval Training Station. Sullavan also appeared in soundies and worked as a ghost singer in films. She was involved in a legal dispute over the song "Rum and Coca-Cola," which she co-authored, resulting in a settlement.

Sullavan married George Sontag in 1941. She passed away in 2003 in Palm Desert, California.
