Robert Stell Lemmon (born 26 June 1885 in Englewood, New Jersey; died 3 March 1964 in Wilton, Connecticut), often Robert S. Lemmon in publications, was an American writer and naturalist. He wrote and lectured on domestic dogs, gardening, wildlife, wild flowers and trees. Most of his writing was non-fiction, but in 1923 he also wrote an adventure short-story called The Bamboo Trap, about an American entomologist caught in a cave in the Ecuadorian jungle.
