About Jefferson

Located in the southeastern tip of South Dakota, Jefferson offers a quiet, relaxed pace of life with Sioux City just a 15-minute drive away. With around 500 residents, it has the feel of a close-knit country town while still sitting conveniently within the Sioux City metro area. The community got its start in 1859 with a group of French-Canadian homesteaders, and its position near the Missouri and Big Sioux rivers gives it plenty of open space and rural charm.
