De Smet | USA South Dakota

De Smet is an incorporated city and the seat of Kingsbury County, situated on the high prairies of east-central South Dakota. Known worldwide as the "Little Town on the Prairie," it is defined by its deep literary connection to Laura Ingalls Wilder, its quintessential Midwestern charm, and its role as a pilgrimage site for fans of pioneer history.

Historical Timeline

Inhabited by the Dakota Sioux. Founded in 1880 during the western expansion of the Chicago and North Western Railroad; named for Pierre-Jean De Smet, a Belgian Jesuit missionary. A critical historical event was the arrival of the Charles Ingalls family in 1879. De Smet served as the setting for five of Wilder’s "Little House" books, including The Long Winter and Little Town on the Prairie. In the 20th century, the city transitioned into a stable agricultural and manufacturing hub while leaning heavily into heritage tourism. In the 21st century, it remains a globally recognized cultural landmark for 19th-century frontier life.

Demographics & Population

The 2026 population is approximately 1,040. The demographics are predominantly White (97%). The economy is driven by Agriculture (corn and soybeans), Manufacturing (signage and building materials), and Heritage Tourism.

Facts & Legends

De Smet once had a flourishing Opera House, which today is the site of Ward’s Store & Bakery. Historically, the "Long Winter" of 1880–1881 was so severe that the town was cut off from the railroad for months, forcing residents to grind wheat in coffee mills to survive. A local legend involves the "Ghosts of the Surveyors' House," with visitors often reporting the scent of Ma's cooking or the sound of an 1880s fiddle playing in empty rooms. Another legend suggests that "Pa" Ingalls buried a small "treasure" of coins beneath the threshold of the Third Street house for good luck.
