Ohio Territory

The United States never had an organized territory named Ohio Territory. This term may refer to:

  • Northwest Territory incorporating what is today the state of Ohio between 1787 and 1803
  • Ohio Country, incorporating most of Ohio, the southern peninsula of Michigan, western Pennsylvania and southeastern Indiana prior to 1787
  • loosely, the Ohio River Valley in colonial times
  • incorrectly or informally, lands within the boundary of the state of Ohio after statehood in 1803
