Roger Conant (May 6, 1909 – December 19, 2003) was an American herpetologist, author, educator and conservationist.
He was Director Emeritus of the Philadelphia Zoo and adjunct professor at the University of New Mexico.
When he was a teenager he took a job at a local zoo to help his mother make ends meet, which, along with participating in the Boy Scouts of America, began his lifelong passion for reptiles.
He was president of the American Association of Zoological Parks and Aquariums from 1946 to 1947 and helped found the Philadelphia Herpetological Society in 1952.
A significant bequest from his estate helped put the Chihuahuan Desert Research Institute on a solid financial footing.
