Nathaniel Massie (December 28, 1763 – November 13, 1813) was a frontier surveyor in the Ohio Country (including the Virginia Military District) who became a prominent land owner, politician, and soldier. He founded fourteen early towns in what became the State of Ohio, including its first capital, Chillicothe. In 1807, the Ohio General Assembly declared him the winner of the election for governor, but he refused the office.
