Watson is an unincorporated community and census-designated place (CDP) in Livingston Parish, Louisiana, United States.

Several buildings were used for classes there, until the present site was purchased and a two-story school built.

The church history states that W.C. Newsom, Huff Jones, George Nesom, J.B. Easterly and James Chandler erected a new building shortly after the Civil War fire.

According to the U.S. Census Bureau, the Watson CDP has an area of 0.97 square miles (2.5 km2), all of it recorded as land.
