The Sac or Sauk are a group of Native Americans of the Eastern Woodlands culture group. They lived mostly in the region of what is now Green Bay, Wisconsin. This was when they were first met by the French in 1667.
They have three federally recognized tribes, together with the Meskwaki (Fox), in Iowa, Oklahoma and Kansas.
