Rainsville was platted on April 16, 1833, by Isaac Rains, who had built a mill here the previous year; the town was named for him. A post office was established on February 5, 1836, and closed on September 15, 1904.
For many decades, there was a school in Rainsville that instructed first through eighth grades. Then, in 1974, three tornadoes came through Rainsville and destroyed most of the little town. The school was severely damaged, and most of the homes were damaged or destroyed entirely.
Rainsville is located 4 miles (6.4 km) miles southwest of Pine Village and 2.5 miles (4.0 km) miles east of U.S. Route 41. Big Pine Creek flows from Pine Village, around the north side of the town, and continues to the southwest.
