East Lynn began as a small merchant community known as Twin Creek but eventually grew as a coal town. In 1868, the Adkins Mills Post Office was established and the community was known as Adkins Mills. The Big Sandy, East Lynn & Guyan Railroad was formed in 1903 and merged with the Norfolk and Western in 1908. Also in 1908, East Lynn was incorporated. East Lynn continued to grow in the 1910s and at various times had three movie theaters, doctors, lawyers, and a detective agency. In the late 1910s, the residents decided to abandon the town's charter, and the town became unincorporated once again. Much of the town was destroyed by fire in November 1919. East Lynn was rebuilt; however, it burned once again in February 1955. The coal mines shut down in the 1960s, and the railroad left, leaving the town dilapidated. The East Lynn Lake was created in the 1960s by the Army Corps of Engineers. Rockspring Development reopened a mine near East Lynn on Camp Creek, but as of 2005 it has not created any new growth for the town itself.
