The community was originally named Osawkee and became Jefferson County's original county seat in 1855. The word Ozawkie is derived from the Sauk or Saukee Indians.
In 1930, there were rumors the US Army Corps of Engineers building a dam and relocation would be required. However, it was only in 1954 that the Perry Dam Project was approved. Since Ozawkie was not incorporated, the US Government would not relocate it. Citizens came together to form a non-profit organization to help move Ozawkie. In 1966, Ozawkie was relocated to higher ground west of the original town site and a water tower, school and 26 homes were built.
