Koenig Valley () is an ice-free valley just east of Mount Thor in the Asgard Range, Victoria Land. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Ervon R. Koenig, a scientific leader at McMurdo Station with the 1972 winter party and station manager there in the 1973-74 and 1974-75 seasons.
