Wohlschlag Bay () is a large bay indenting the western side of Ross Island, Antarctica, and lying between Harrison Bluff and Cape Royds. It was first charted by the Discovery Expedition under Robert Falcon Scott, 1901–1904, then named by the Advisory Committee on Antarctic Names (US-ACAN) in 1964 for Donald E. Wohlschlag, professor of biology at Stanford University, who outfitted the biology laboratories on the USNS Eltanin and at McMurdo Station.
