George L. Cowgill (born 1929) is an American anthropologist and archaeologist. He is currently professor emeritus at Arizona State University. He received his PhD from Harvard in 1963 with a dissertation on The Post-Classic Period in the Southern Maya Lowlands. Most of his career has been devoted to research at the ancient Mexican city of Teotihuacán. He taught at Brandeis University between 1960 and 1990. Cowgill has made important contributions in a number of areas, including the archaeology of Mesoamerica, the comparative study of early states and cities, and quantitative methods in archaeology.
George Cowgill and his twin brother, linguist Warren Cowgill (d. 1985), were born near Grangeville, Idaho in 1929. Along with his brother, George Cowgill graduated from Stanford University in 1952 with a degree in physics.
Cowgill was selected as the 1992 Distinguished Lecturer in Archaeology by the American Anthropological Association. In 2004 he was awarded the Alfred Vincent Kidder Award of the American Anthropological Association for his contributions to the archaeology of the Americas. This is one of the most prestigious awards in the field of archaeology.
Cowgill's major archaeological fieldwork and analysis has been centered on Teotihuacán. With René Millon, Cowgill spent years systematically mapping the city of Teotihuacán in the Valley of Mexico near modern Mexico City. In the 1960s he compiled an extensive database of the artifacts collected in the survey. This was one of the first large-scale archaeological databases, and it continues to be used for research today. In the late 1980s, Cowgill co-directed excavations at the Feathered Serpent Pyramid at Teotihuacán with Saburo Sugiyama and Rubén Cabrera. Several of Cowgill's published articles on Teotihuacán are among the most important syntheses of archaeological information on this ancient city.
