The glacier was named by the Advisory Committee on Antarctic Names in 1992 after William A. Cassidy, Department of Geology and Planetary Science, University of Pittsburgh, who in 13 field seasons, 1976–90, led United States Antarctic Research Program teams in the investigation and collection of Antarctic meteorites from diverse sites through Victoria Land and southward to Lewis Cliff, adjacent to the Queen Alexandra Range.
