Oak Harbor is a city located on Whidbey Island in Island County, Washington, United States. The population was 24,622 at the 2020 census. Oak Harbor was incorporated on May 14, 1915.

The Lower Skagit people have inhabited Oak Harbor (Lushootseed: təqucid)^[6] and the nearby Crescent Harbor (Lushootseed: č̓itusəb)^[6] since time immemorial.^[7] There were several villages in the vicinity, and the modern settlement of Oak Harbor was built over one such village.^[7]

In the early 1850s, two settlers staked claims where the city now stands—Zakarias Martin Toftezen, a shoemaker from Norway; C.W. Sumner from New England.^[8] Irish and Dutch immigrants also arrived and settled in the area. Oak Harbor was named for the area's Garry Oak trees and was incorporated in 1915 with a population of 401. Houses and businesses sprouted up along the shores of Oak Harbor as the pioneers relied entirely on water transportation until the 1900s. For the next 30 years, steamers and freighters carried passengers and freight from the Island to the mainland and back as well as Fidalgo Island to the north. The city grew following the completion of Deception Pass Bridge on July 31, 1935, and Naval Air Station Whidbey Island on September 21, 1942.^[9] The bridge, which linked Whidbey Island to Fidalgo Island and the mainland, was a Public Works Administration project built by the Civilian Conservation Corps. A nearby state park with 4,100 acres (17 km²) of forest, campsites, and trails was also developed.

According to the United States Census Bureau, the city has a total area of 9.47 square miles (24.53 km²), of which 9.42 square miles (24.40 km²) is land and 0.05 square miles (0.13 km²) is water.^[10] Access to the island by land is only available by driving through Deception Pass. Other ways to travel to Whidbey Island include flying or utilizing a ferry service. The Mukilteo–Clinton ferry provides service connecting the southern end of Whidbey Island to the area immediately north of Seattle, while the Coupeville-Port Townsend ferry connects to the Olympic peninsula.^{[citation needed]}

Surveys of shorelines throughout the Puget Sound region have indicated that 58% are "unstable". Average retreat rates range from one to eight centimeters per year and shores in the Puget Sound area, composed of unconsolidated sediment, erode 10 to 100 times faster than rocky shoreline.^[11]

Oak Harbor has a Mediterranean climate (Köppen Csb) characterized by warm, dry summers and cold, though not severe, and damp winters. Due to the Olympic rain shadow, the region that the region is much drier than most of the Pacific Northwest west of the Cascades.
