Gilmore is an unincorporated community in Le Flore County, Oklahoma, United States. The town, formerly incorporated, boasted a small post office, city hall, and Mayor Pratt McMillin, a rancher and oil distributor who died in April 2001, aged 84. The primary population of Gilmore lives around the intersection of Nail Creek Road and Gilmore Road just east of Poteau and north of Monroe, although in recent years, multiple houses have been built along Nail Creek Road west of Gilmore Road, expanding the community towards the town of Poteau. The town is home to the Vaughn Memorial Cemetery which was adjacent to the Double Branch Baptist Church until the church burned down in 2004.
