Barbara Jane Bates (August 6, 1925 – March 18, 1969) was an American singer and actress, best known for her portrayal of Phoebe in the 1950 drama film All About Eve and as Katy Morgan on It's a Great Life (1954–1956).

The eldest of three daughters, Bates was born in Denver, Colorado. While growing up in Denver, she studied ballet and worked as a teen fashion model. The shy teen was persuaded to enter a local beauty contest and won, receiving two round-trip train tickets to Hollywood, California. Two days before returning to Denver, Bates met Cecil Coan, a United Artists publicist, whom she would later marry.
