Brinkley is the most populous city in Monroe County, Arkansas, United States. Located within the Arkansas Delta, Brinkley was founded as a railroad town in 1872. The city has historically been a transportation and agricultural center in the region, more recently developing a reputation for outdoors recreation and the ivory-billed woodpecker. Birding has become important to the city and region following the discovery of the ivory-billed woodpecker in 2004, a species thought to be extinct 60 years earlier. Located halfway between Little Rock and Memphis, Tennessee, the city has used the slogan "We'll Meet You Half-Way" in some of its advertising campaigns. The population was 3,188 at the 2010 census.
