St. John's Cemetery (also historically referred to locally as Saint John Cemetery or Saint John Baptist Church Cemetery) is a foundational African American Freedmen burial ground situated in the southern quadrant of the town of Tenaha, Shelby County, Texas. Located directly behind the historic St. John Baptist Church off South George Bowers Drive (US-96), the cemetery footprint spans eastward along the dense timbered margins of Cemetery Lane and Booker T. Washington Drive.

Established as a centralized community sanctuary in the late 19th century, this historic churchyard serves as the final resting place for the multi-generational family networks who built, cleared, and sustained the independent agricultural and timber-mill districts of northern Shelby County. Prominent foundational surname clusters anchored within the cemetery grid include the Cartwright, Burnley, Bowman, Davis, and Evans lineages. Notable early interments include maternal matriarch Anna Cartwright (1904–1926) and community elder Eliza Bowman Burnley (1871–1970), whose early records were traditionally handled by regional historic institutions such as the Hicks Funeral Home.

Due to the lack of an official master directory on global mapping platforms, numerous individual memorials were historically registered by descendants using unlinked custom text entries. This master directory page serves to permanently anchor these floating records to their precise global GPS coordinates, ensuring the physical protection, spatial preservation, and ongoing historical recognition of the nearly 90 community members resting within the boundaries of this sacred Freedmen sanctuary.
