The Eramosa Karst is a provincially significant Earth Science Area of Natural and Scientific Interest in Ontario, Canada, located in Stoney Creek, a constituent community of the City of Hamilton, and immediately south of the Niagara Escarpment.

It exhibits sixteen different karstic geological features, of which seven are provincially significant, and is considered to be the best example of karst topography found in Ontario. The area is composed of parcels of land that are provincially, municipally and privately owned. It received ANSI-ES designation on February 13, 2003.
