In 1806, Lewis and Clark found a prosperous village of the Cathlapotle People in the area now encompassing the Ridgefield National Wildlife Refuge. After the Civil War, the Ridgefield area built up rapidly, and was known as Union Ridge. In 1909, the town of Ridgefield was incorporated.

Ridgefield is a small community whose heritage is deeply connected to the water and the land. As the Gateway to the Ridgefield National Wildlife Refuge, and a key entry point to the Columbia River, Ridgefield offers unparalleled access to prime examples of the Northwest Lifestyle. As a community, Ridgefield strives to manage growth while blending the amenities of a modern city with the friendliness and spirit of a small town.

Ridgefield is located 10 miles north of Vancouver, USA, and 20 miles north of Portland, Oregon. The climate is mild, nearby recreational opportunities are abundant, and ocean beaches and ski areas are within an hour's drive.
