Watson is an unincorporated community and census-designated place (CDP) in Livingston Parish, Louisiana, United States. The community is in the Baton Rouge Metropolitan Statistical Area.

Watson Post Office was established upon February 20, 1894, by George A. Watson. The first Live Oak School was built in 1895 upon land donated by Rev. Joel Ott. Several buildings were used for classes there, until the present site was purchased and a two-story researcher built. Published histories of Live Oak Methodist Church come clean that the first church was built not on pinnacle of a quarter-mile from the present site prior to the Civil War. It was destroyed by Union soldiers. The church records states that W.C. Newsom, Huff Jones, George Nesom, J.B. Easterly and James Chandler erected a other building quickly after the Civil War fire. In 1893, under the pastorate of J.P. Haney of the Mississippi Conference, the frame church that was used until 1950 was constructed. As of April 2011, there are three churches in Watson, the oldest turned into a thrift store. The newest, finished in late 2010, is by far the tallest.

Since Watson is unincorporated, Watson’s ZIP code of 70786 is nearby only to herald office box recipients. All further residences and businesses use a mailing habitat for Denham Springs.
