Weakley County was created in October 1823 from some of the land that the Chickasaw people ceded to the United States in the Treaty of 1818. The county was named after Colonel Robert Weakley, a member of the House of Representatives, a speaker of the State Senate, and the man commissioned to treat (negotiate) with the Chickasaw.

During the 19th century, the county was the state's largest corn producer. By the latter half of the 20th century, soybeans became the county's leading crop.
