The Brassfield Formation, named by A.F. Foerste in 1906, is a limestone and dolomite formation exposed in Ohio, Kentucky, Indiana, Tennessee and West Virginia in the United States. It is Early Silurian (Aeronian, Llandoverian) in age and well known for its abundant echinoderms, corals and stromatoporoids. In Ohio, where the unit has escaped dolomitization, the Brassfield is an encrinite biosparite with numerous crinoid species.
