Founded in 1878 by five charter members, the church originally was named Kings Chapel. It was also known as Pleasant Hill Missionary Baptist Church and as Dry Fork Church. The church deacons purchased land at this site in 1899, and when a post office for the community was granted under the name Olin, the church was renamed Olin Baptist Church. Serving the community for well over a century, the church has offered a variety of worship and educational programs and has supported both domestic and foreign missionary endeavors.
