Locust is an unincorporated community located in Carroll County, Kentucky, United States.

Locust is located west of the Little Kentucky River and southeast of Hunter's Bottom.

It served as the commercial, religious, and educational center of northwest Carroll County from 1880 to 1940.

By the time owner James Mosgrove died in 1882, the store was purchased by John and W. Harvey Conway and expanded its agricultural supplies.

During the Great Depression, many farmers in Locust went bankrupt due to the failure of the tobacco market.
