Pine Grove United Methodist Church was located at 3335 Louisiana Highway 449, Pine Grove, Louisiana.

The church dates its history back to the acquisition of land. On March 13, 1861, Thomas and Nancy Bennett sold the church two acres of land. A church was built on the property. The earliest grave in the cemetery dates back to 1868. Though once surrounded by pine trees in rural St. Helena Parish, the church now sits along a highway.

The earliest record of a pastor assigned to the church is in 1894. Like most Methodist churches in the Florida parishes, they were in the Mississippi Conference until the 1890s. Sometime around 1940, the church became a full-time charge. Services were held at eleven on Sunday mornings and later that evening. In 1963, plans began for a new sanctuary. It was soon completed, and the first services held in the new structure were on September 6, 1964. The dedication service was the following year, on November 7, 1965. Though a parsonage was maintained for many years, changes resulted in the elimination of the parsonage in 1978. In 2002, the church had a vision to add more room for activities and fellowship. The existing fellowship hall was expanded. Work was completed and the new facility was consecrated on April 27, 2003.

Pine Grove United Methodist Church disaffiliated from the United Methodist Church in November 2022.
