Saginaw County, officially the County of Saginaw, is a county located in the U.S. state of Michigan. As of the 2020 Census, the population was 190,124. The county seat is Saginaw. The county was created by September 10, 1822, and was fully organized on February 9, 1835. The etymology of the county's name is uncertain. It may be derived from Sace-nong or Sak-e-nong, as the Sauk tribe is believed by some to have once lived there. A more likely possibility is that it comes from Ojibwe words meaning "place of the outlet" –sag and ong. See List of Michigan county name etymologies.
