Lonoke is the second most populous city in Lonoke County, Arkansas, United States, and serves as its county seat. According to 2005 Census Bureau estimates, the population of the city is 4,553. It is part of the Little Rock–North Little Rock–Conway Metropolitan Statistical Area.
Lonoke's history begins with the advance of Union troops through Central Arkansas during the American Civil War. The town of Brownsville was burned to the ground by Union forces after the retreat of Confederate forces westward to Little Rock. After the war, it was decided by the city leaders of Brownsville that a new town should be formed by the nearby railroad so that those who wished to stay could do so.
According to local legend, the town was named for a large red oak tree that was found while trees were being chopped down in order to build houses. The official name of the city was originally Lone Oak. However, due to a misprint in the Lonoke Democrat newspaper, the town's name was printed as Lonoak. Eventually, this misspelling became further misspelled as Lonoke.
