Archie Carr (June 16, 1909–May 21, 1987) was a Professor of Zoology at the University of Florida.

He was the son of a Presbyterian pastor and spent his growing up years in Mobile, Alabama, Fort Worth, Texas and Savannah, Georgia. He studied zoology at the University of Florida, eventually specializing in herpetology. He further refined that interest to the study of turtles and eventually became one of the world's foremost authorities on sea turtles.

He wrote numerous books and articles, including Ulendo: Travels of a Naturalist in and out of Africa, High Jungles and Low, So Excellent a Fishe (about his green turtles), The Windward Road and several Time-Life books such as The Everglades and The Reptiles. He was also the author of the Handbook of Turtles, and with Coleman J. Goin, Guide to the Reptiles, Amphibians and Freshwater Fishes of Florida. While a serious scientific and nature writer, he also had a remarkable sense of humor, which led him to publish the parody of scientific taxonomic keys - his A Subjective Key to the Fishes of Alachua County, Florida, affectionately known as the "Carr Key".

Carr became a bit of a legend at the University of Florida and students vied with one another to take his Community Ecology course in which they were involved in several major and minor field trips around northern Florida and southern Georgia. Listening to Dr. Carr talk about the sand pine scrub near Ocala or his comments as he guided students through the Okefenokee Swamp in canoes was a great privilege.

Carr was also known for his efforts in conservation, especially for sea turtles. In this activity he was often joined in by his wife Marjorie (who was a major advocate for conservation in her own right).
