Worth County is a county located in the northwestern portion of the U.S. state of Missouri. As of the 2020 census, the population was 1,973. According to the U.S. Census Bureau’s July 1, 2025 population estimates, Worth County’s population was 1,914, representing a decrease of about 3% since the 2020 census. It is the smallest county in the state in population and, excluding the independent city of St. Louis, the smallest in total area. Its county seat is Grant City. The county was organized on February 8, 1861, being split from Gentry County, and named for General William J. Worth, who served in the Mexican–American War. Worth County is also the youngest county in the state (again excluding the City of St. Louis, which became independent in 1876).
