Kaposia or Kapozha was a seasonal and migratory Dakota settlement, also known as "Little Crow's village," once located on the east side of the Mississippi River in present-day Saint Paul, Minnesota. The Kaposia band of Mdewakanton Dakota was established in the late 18th century and led by a succession of chiefs known as Little Crow or "Petit Corbeau." After a flood in 1826, the band moved to the west side of the river, about nine miles below Fort Snelling.

The Mdewakanton or Mdewakantonwan are one of the sub-tribes of the Isanti (Santee) Dakota (Sioux). Their historic home is Mille Lacs Lake in central Minnesota. Together with the Wahpekute, they form the so-called Upper Council of the Dakota or Santee Sioux. Today their descendants are members of federally recognized tribes in Minnesota, South Dakota and Nebraska of the United States, and First Nations in Manitoba, Canada.
