Frank Morton Carpenter (September 6, 1902 – January 18, 1994) was an American entomologist and paleontologist. He received his PhD from Harvard University, and was curator of fossil insects at the Harvard Museum of Comparative Zoology for 60 years. He studied the Permian fossil insects of Elmo, Kansas, and compared the North American fossil insect fauna with Paleozoic taxa known from elsewhere in the world. A careful and methodical worker, he used venation and mouthparts to determine the relationships of fossil taxa, and was author of the Treatise volume on Insects. He reduced the number of extinct insect orders then described from about fifty to nine.
