Betty Hall Jones, born Betty Hall Bigby (January 11, 1911 – April 20, 2009), was an American pianist and singer. She was born in Topeka, Kansas.
Jones's father was George Arthur Bigby, a cornetist and leader of a brass band. She learned piano from her uncle in California, where she was raised after her family moved there when she was a child. She married a banjoist whose last name was Hall in 1926, but had divorced by 1936, when she got a job as a backup pianist for Buster Moten in Kansas City.
