Betty Bennett (born October 23, 1921) is an American jazz singer.
Her first major signing was with the Claude Thornhill band in 1946, the band in which her husband, bassist Iggy Shevak, was playing. Shortly after her husband left to join Alvino Rey, Bennett followed him there. In 1949, she joined Charlie Ventura's band before going on to join Benny Goodman in 1959.
Her second album featured arrangements by Shorty Rogers and her second husband, André Previn. Bennett later married guitarist Mundell Lowe.
