Licking County is located in the central portion of the U.S. state of Ohio. At the 2020 census, the population was 178,519. Its county seat is Newark. The county was formed on January 30, 1808, from portions of Fairfield County.

It is named after the Licking River, which is thought to be named for the salt licks that were in the area. However, one account explains it as an English pronunciation of the river's indigenous Delaware name W'li/'ik'/nk, which means "where the flood waters recede".

Licking County is part of the Columbus, OH Metropolitan Statistical Area.
