Oregon Route 453 (OR 453) is an Oregon state highway running from OR 454 near Adrian to State Line Road on the Idaho state line near Adrian. OR 453 is known as the Adrian-Arena Valley Highway No. 453 (see Oregon highways and routes). It is {{convert|3.19|mi|km}} long and runs northwest to southeast in a stairstep pattern, entirely within Malheur County.

OR 453 was established in 2003 as part of Oregon's project to assign route numbers to highways that previously were not assigned, and, as of July 2018, was unsigned.
