Rainier is a city in Columbia County, Oregon, United States. The city’s population was 1,895 at the 2010 census. Rainier is on the south bank of the Columbia River across from Kelso and Longview, Washington.

Rainier is surrounded by a number of rural communities. In the past, these places acted as separate communities. Today, most businesses and services have left these rural sites, and the communities are part of a large unincorporated area that receive services out of Rainier. These communities include Fern Hill, Hudson, Alston, Apiary, Goble, and Prescott. Except for Prescott, which is an incorporated city (despite having neither a post office nor a separate telephone exchange), little remains to identify these places today other than left-over identifying signs or historic landmarks, such as abandoned or converted school buildings. Residents here may say they live in Rainier or will alternatively use the name of the individual community.
The Lewis and Clark Bridge spans the Columbia River, linking Rainier to Longview, Washington. It is the only bridge, that spans the entire width of the river, between Portland and Astoria, Oregon.
