Gregory Forth is a Canadian anthropologist and Fellow of the Royal Society of Canada. He is professor emeritus at the University of Alberta, where he taught from 1986 to 2019. He received his DPhil from the University of Oxford in 1980.
His research centers on the peoples of eastern Indonesia, particularly the Nage and Kéo of Flores island. Over four decades of fieldwork, his interests have encompassed ethnozoology, human-animal relations, symbolic anthropology, and oral tradition.
His most recent book, Between Ape and Human (2022), examines indigenous accounts of small-bodied hominoids on Flores and their possible connection to Homo floresiensis—accounts he began documenting years before the 2003 fossil discovery.
