Wallisville is an unincorporated town in northern Chambers County, Texas, United States.

A military settlement, known as "El Orcoquisac", consisting of the Spanish fort, Presidio San Augustín de Ahumada and its complementing partner, Mission Nuestra Señora de la Luz, was established in 1756, on the east bank of the Trinity River near present-day Wallisville, upon the former site of an early French trading post.

[6] The climate in this area is characterized by hot, humid summers and generally mild to cool winters.

[8] Wallisville had a school in 1869 and remained standing for the Methodist congregation and several others to hold church services in.

[10] This organization operates for the preservation, restoration, and study of the Wallisville Townsite and the El Orcoquisac Archeological District, two sites that are listed in the National Register of Historic Places.
