Donald F. Tuzin (June 14, 1945 – April 15, 2007) was an American social anthropologist best known for his ethnographic work on the Ilahita Arapesh, a horticultural people living in northeast lowland New Guinea, and for comparative studies of gender and sexuality within Melanesia. Tuzin was born in Chicago, Illinois, grew up in Winona, Minnesota, and spent his teen years again in Chicago. He received his B.A. from Western Reserve University in Ohio (shortly before its merger with Case Institute of Technology), where he became interested in anthropology and participated in the excavation of Native American archaeological sites left by the Mound Builders. He also received his master's degree from Case Western Reserve.
