Blacklick is a small unincorporated community in southern Jefferson Township, Franklin County, Ohio, United States. The tiny community began as a railroad station and is situated at the intersection of the railroad and High Street (State Route 605) just north of Broad Street in eastern Franklin County. Blacklick Creek gently flows through Blacklick and serves as the village's namesake. The Blacklick Post Office (zip code 43004) used to be within the village but has moved just south of the village on Reynoldsburg-New Albany Road.
