Othniel Looker (October 4, 1757 – July 23, 1845) was a Democratic-Republican Party politician from Ohio.

[5] He enlisted with the New Jersey militia in 1776, and served out the remainder of the American Revolutionary War as a private.

[2] While serving as Speaker of the Ohio Senate from 1813 to 1814, Looker was concurrently elevated to the governorship, after then-Governor Return J. Meigs Jr. resigned to become Postmaster General.

The Othniel Looker House is open to the public, free of charge, on a few dates during each year, and special tours can be arranged for school groups.
