Mercer was founded in 1888 by T. B. Mercer, for whom the community is named, at an intersection of a stagecoach road and the Tennessee Midland Railroad. Mercer erected a general store at the intersection, and it was followed in 1894 by a railroad station officially named Mercer. By the turn of the century, a lumber company and several churches had been established in the area. The community eventually had a bank and an opera house, but the former failed in 1933 and the latter burned down in the late 20th century.
