Dominic Joseph Fontana (born March 15, 1931, in Shreveport, Louisiana), is an American musician best known as the drummer for Elvis Presley for 14 years. He played on over 460 RCA cuts with Elvis.

Nicknamed "D. J.", he was employed by the Louisiana Hayride to be an in-house drummer on its Saturday night radio broadcast. In October 1954 he was hired to play drums for Presley, and that marked the beginning of a fifteen-year relationship. He performed on the NBC television special known as the '68 Comeback Special.
