Vilonia is a city in Faulkner County, Arkansas, United States. Its population was 3,815 at the 2010 census, up from 2,106 at the 2000 census. It is part of the Little Rock–North Little Rock–Conway Metropolitan Statistical Area.
When Vilonia was originally settled in the 1860s, it was listed as Cypress Township, but settlers quickly named it Vilsonia, or "land of two valleys". When the local Masons applied for national affiliation, a transcription error removed the 's', leaving the town, officially, Vilonia. It was incorporated on August 23, 1938, under the leadership of Mayor Thomas Henry Hill.
A small portion of the town was destroyed by a tornado on the evening of April 25, 2011. The devastated area was a mobile home park. The tornado was confirmed and rated high end EF2 by National Weather Service survey crews. Four people were killed in the Vilonia area as a result of the twister.
On April 27, 2014 in the late evening hours, a violent EF4 tornado slammed through Mayflower and continued on into Vilonia just before 8 PM. Sixteen people were killed, several homes in one subdivision were swept clean off their foundations, a 15-ton fertilizer tank was thrown 3/4 of a mile, and several businesses were damaged or destroyed, including the new Vilonia Intermediate School, which had been set to open in the fall. The rating is disputed due to the fact that houses were completely obliterated.
