Oregon Route 452 (OR 452) is an Oregon state highway running from OR 201 near Adrian to State Line Road at the Idaho state line. OR 452 is known as the Parma Spur No. 489 (see Oregon highways and routes). It is {{convert|2.75|mi|km}} long and runs east–west, entirely within Malheur County.

OR 452 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.
