Salem is a Livingston county city on US 60 about ten miles northeast of Smithland. It was established in the early nineteenth century. The source of the name isn't known certainly, but it may be from the home of some early settlers in North Carolina. The county seat moved to Salem from Centerville (now in Crittenden county) in 1809 and in 1842 moved to Smithland. Salem was incorporated in 1869. The Salem post office opened circa 1807. The population in 2010 was 752.
