U.S. Route 33 (US 33) is a United States Numbered Highway running from near Elkhart, Indiana, to Richmond, Virginia. Within the state of Ohio, it is a predominantly southeast–northwest highway running from west of Willshire before crossing over into West Virginia via the Ravenswood Bridge over the Ohio River. The route runs through largely rural territory throughout most of the state's west-central, central, and southeastern regions, although it also passes through large portions of downtown Columbus.

US 33 enters Ohio from Indiana, to the west, near Willshire in Van Wert County as a two-lane highway, continuing southeast through Mercer County, crossing US 127, then entering Auglaize County, joining limited-access Ohio Route 29 (SR 29) briefly near St. Marys, continuing east as a four-lane parkway, then a controlled-access highway near Wapakoneta, where it intersects Interstate 75 (I-75).
