Blairstown is an unincorporated community in East Feliciana Parish, Louisiana, United States. The community is located less than 4miles north of Pride and 8miles southeast of Clinton.
It is speculated that the community is named after John Insley Blair. In the fall of 1866 a Presbyterian missionary named Rev. John Arndt Reiley migrated to the community from Blairstown, New Jersey.[1]
