Bob Eberly (July 24, 1916, Mechanicville, New York – November 17, 1981, Glen Burnie, Maryland) was a big band vocalist, best known for his association with Jimmy Dorsey and his duets with Helen O'Connell.

Eberly was born Robert Eberle, but changed the spelling of his surname slightly to Eberly. His younger brother Ray was also a big-band singer, most notably with Glenn Miller's orchestra. Their father, John A. Eberle, was a policeman, sign-painter, and publican (tavern-keeper). Another brother, Al, was a Hoosick Falls, New York village trustee.
