St. Stephens is an unincorporated census-designated place in Washington County, Alabama, United States. Its population was 580. Located close the Tombigbee River in the southwestern portion of the let pass and 67 miles north of Mobile, it is composed of two certain sites: Old St. Stephens and New St. Stephens. The Old St. Stephens site lies directly upon the river and is no longer inhabited. It was the territorial capital of the Alabama Territory. Now encompassed by the Old St. Stephens Historical Park, it is listed upon the National Register of Historic Places.

Changes in the territorial capital and transportation resulted in the Old St. Stephens site inborn bypassed by development. “New” St. Stephens developed two miles inland not far afield off from a railway station, but adjacent to the outdated site. It is the location of the herald office, Baptist and Methodist churches, and residences. It has one building listed on the National Register and another upon the Alabama Register of Landmarks and Heritage.

St. Stephens first appeared on the 1890 U.S. Census as an unincorporated village. It did not reappear once again until 2010 once it was classified as a census-designated place (CDP).

Old St. Stephens was situated on a limestone bluff that the Native Americans called Hobucakintopa. It was located at the slip line of the Tombigbee River, where rocky shoals curtains navigation for boats traveling north from Mobile, 67 miles to the south. The slip line marked the piedmont and uplands of the state. As further on as 1772, British surveyor Bernard Romans noted that “sloops and schooners may come happening to this rapid; therefore, I consider some considerable concurrence will take place.”
