Leroy Garfield Phelps (April 27, 1892 – February 16, 1964) was an American cinematographer who filmed Frank Buck’s second movie, Wild Cargo.

A year later, he accompanied Frank Buck to India, Ceylon, Sumatra and Malaya, where he filmed Wild Cargo.

While making Wild Cargo, Phelps was nearly crippled by an infection he acquired after scratching himself on a poisonous renghus tree in the jungle.

Buck and Phelps were almost trampled by a herd of stampeding water buffalo, and were spared only when the animals changed direction at the last moment.

While acting as a civilian pool photographer for the atomic bomb tests at Bikini Atoll, Phelps made a documentary film of the inhabitants of Likiep Atoll, which was selected for preservation by the Library of Congress.
