How to read and use this map

County lines are administrative boundaries, not postal routes. A mailing address can use a city name associated with a neighboring area, and ZIP codes can cross county lines. When you need to identify a county for an address, confirm it with an official geocoder or local government source.

For classroom or planning use, print directly from this page. If labels become crowded, choose landscape orientation and reduce page margins. The underlying vector lines remain crisp at different sizes.

Frequently asked questions

How many counties are in Oregon?

Oregon has 36 counties in the U.S. Census Bureau’s 2025 cartographic boundary file.

Can I print this Oregon county map?

Yes. Choose Print map and use landscape orientation for the widest map. Because the map is SVG, its boundary lines stay sharp when scaled.

Are these legal survey boundaries?

No. This is a generalized reference map. Property, parcel, election, and legal boundary questions should be checked with the relevant state or local agency.
