Dallas is an unincorporated community in Polk County, Arkansas, United States.

They settled near Dallas, surviving off the area's abundant wild game, and building shelters from its rich timber resources.

Dallas became a regional center due to its location along Long's Trail, a stagecoach route which connected to the Butterfield Overland Mail Trail to the north, and passed west into what is now Oklahoma.

At one time, Dallas had three mills, livery stables, boarding houses, two churches, several stores, and a weekly newspaper.

A special election was held in 1898, and residents voted to move the county seat to Mena.
