Oregon is home to 241 incorporated municipalities, each with its own unique character, government, and role in shaping the state’s communities. From Portland, the largest city, to Greenhorn, the tiniest with just a handful of residents, Oregon’s municipalities range widely in size, culture, and geography. But what exactly is a municipality in Oregon? And how are these cities distributed across the state?
This guide provides a full list of Oregon municipalities, explains the legal framework behind them, and highlights key trends shaping urban and rural life.
What Is a Municipality in Oregon?
In Oregon, a municipality is essentially an incorporated city. Unlike some states that distinguish between towns, villages, or boroughs, Oregon law treats all incorporated local governments simply as “cities,” regardless of population or size.
- Incorporation process: Communities become municipalities through a voter-approved process outlined in the Oregon Revised Statutes (ORS Chapter 221).
- Home rule authority: Thanks to Oregon’s Constitution (Article XI, Section 2), cities may adopt a home rule charter, giving them broad authority to govern local matters such as land use, utilities, taxation, and public safety.
- Uniform designation: Whether it’s Portland with 640,000+ people or Greenhorn with fewer than 10, Oregon calls them all “cities” — no official “town” or “village” designations exist.

Regional Breakdown of Oregon Municipalities
Oregon’s municipalities reflect the state’s varied geography from coastal towns to mountain communities to sprawling valley cities.
- Willamette Valley: The most densely populated region, home to Portland, Salem, Eugene, and many mid-sized cities like Corvallis and Albany. This region holds over 70% of Oregon’s population.
- Oregon Coast: Dozens of small municipalities, including Astoria, Newport, Florence, and Coos Bay, rely heavily on tourism, fishing, and shipping.
- Central Oregon: Led by Bend and Redmond, this area has seen explosive growth in the past two decades, driven by outdoor recreation and tech migration.
- Eastern Oregon: Sparsely populated with many small towns like Baker City, Ontario, and Burns, emphasizing ranching and agriculture.
- Southern Oregon: Medford, Grants Pass, and Ashland anchor this region, known for wine, arts, and Rogue Valley scenery.
👉 Regional patterns show that Oregon’s urban growth is concentrated in the Willamette Valley and Central Oregon, while many rural municipalities face population stagnation or decline.
