The Spirit Lake Massacre (March 8–12, 1857) was an attack by a "Wahpekute" band of Santee Sioux on scattered Iowa frontier settlements during a severe winter.
 Suffering a shortage of food, the renegade chief Inkpaduta (Scarlet Point) led 14 Sioux against the settlements near Okoboji and Spirit lakes in the northwestern territory of Iowa near the Minnesota border, in revenge of the murder of Inkpaduta's brother, Sidominadotah, and Sidominadotah's family by Henry Lott.
 The Sioux killed 35-40 settlers in their scattered holdings, took four young women captive, and headed north.
