The state highway route numbers in the U.S. state of Oregon are the numbers assigned to state highways that are not part of either the national Interstate Highway System or the United States Numbered Highway System. These route numbers are used on maps for navigational purposes. In addition, the Oregon Department of Transportation (ODOT) assigns a system of highway numbers, which correspond to the set of roads maintained by ODOT, are an internal system used in ODOT projects and accounting, and are typically not exposed to the public.
