St.John and Robertsville are two unincorporated communities in Gadsden County, Florida, United States. They are located near the intersection of Old Philadelphia Road and Old Bainbridge Road. Unlike some people think, the communities are not a part of the Mount Pleasant area. They recently had a zipcode change which split the community into two zipcodes, however the community considers itself a part of Quincy. They are approximately 5 miles outside of the city limits of Quincy, Florida. St. John borders the city of Gretna and the Robertsville community borders the Georgia state line, Attapugus, Georgia, Faceville, Georgia and Chattahoochee, Florida. These two communities are usually spoken of and thought of together although they are separate and distinct. St.John is known for its school, St.John's elementary school, the St.John/Robertsville park, the St.John volunteer fire department and most recently the St.John Church of God in Christ,. The church has been a staple in the community for over 50 years but is noted because of its new building on Old Philadelphia highway.
