Three specimens of the Chinese mitten crab, Eriocheir sinensis, were captured commercially by gillnets in Lake Erie in April and May, 1973, and one was taken from a water-intake pipe in the Detroit River in 1965. These are the first published records of this species for North America. The hazard of establishment of this catadromous crab in North America is discussed.
