Ronald Pierce "Ron" Ely (born June 21, 1938) was an American actor and novelist born in Hereford, Texas. Ely is best known for having portrayed Tarzan in the 1966 NBC series Tarzan and for playing the lead role in the 1975 film Doc Savage: The Man of Bronze.

Ely obtained the role after playing various bit-parts, including an airplane navigator in the 1958 film South Pacific and a guest-starring role on Barbara Eden's first television series, the romantic comedy How to Marry a Millionaire. Ely's height (6' 4") and athletic build also won him the title role in the 1975 film Doc Savage, as well as various guest shots. In a 1978 Fantasy Island episode, for example, Ely portrayed Mark Antony in a Roman military short tunic and breastplate that displayed almost as much of his physique as his Tarzan costume had.
