Azalea is an unincorporated community in Douglas County, Oregon, United States, about 10 miles northeast of Glendale on Interstate 5, at an elevation of 1,657 feet. Azalea was named for the abundance of azaleas in the area, including the Azalea occidentalis and the Azaleastrum albiflorum. The name Azalea was used for two different post offices in the upper Cow Creek Valley in Douglas County. A post office named "Starveout" was established in 1888.
