Located five miles north of Guntown, the main street of Baldwyn runs along the county line of Lee and Prentiss counties. The city has the unusual distinction of having been incorporated in four counties. It was incorporated by an Act of the Legislature in Tishomingo and Itawamba counties on April 1, 1861. Tishomingo County was divided into Alcorn, Prentiss and Tishomingo in 1870, while Lee County was formed from parts of Itawamba and Pontotoc counties in 1866. Baldwyn is an outgrowth of the village of Carrollville: when the Mobile and Ohio Railroad was being built during the years of 1848 to 1861, it missed Carrollville by one and one-half miles and the citizens moved to the new town of Baldwyn, which was named for the civil engineer who surveyed the road through the town. Tishomingo, chief of the Chickasaw, lived at old Carrollville but died at Little Rock, Arkansas, in 1839 of smallpoxwhile being moved west with his tribe. The population of Baldwyn was 3,304 in 2017.
