The Jackson County Courthouse is located along Main Street (Arkansas Highway 367) in the center of Newport, Arkansas, the county seat of Jackson County. It is a Late Victorian brick building, with a protruding three-story square tower. It was built in 1892, and is one of the state's oldest courthouses. It was apparently based in part on the Ouachita County courthouse (since demolished), but its architect is not known. The building was listed on the National Register of Historic Places in 1976.
