Island County is a county located in the U.S. state of Washington. As of the 2010 census, its population was 78,506.[1] Its county seat is Coupeville,[2] while its largest city is Oak Harbor.

Its name reflects the fact that it is composed entirely of islands.[3] It contains two large islands, Whidbey and Camano, and seven smaller islands (Baby, Ben Ure, Deception, Kalamut, Minor, Smith, and Strawberry). Island County was created out of Thurston County on December 22, 1852, by the legislature of Oregon Territory,[4][5] and is the eighth-oldest county in Washington. It originally encompassed what are now Snohomish, Skagit, Whatcom, and San Juan Counties.

Island County comprises the Oak Harbor, WA Micropolitan Statistical Area, which is also included in the Seattle-Tacoma, WA Combined Statistical Area.

Island County is divided in many ways between its north and south. While the north (Oak Harbor) is conservative – George W. Bush received almost 65 percent of the 2004 vote and carried all precincts – all southern and central precincts voted for John Kerry. This is probably accounted for by the presence of Naval Air Station Whidbey Island, located north of Oak Harbor. The south-central area (Coupeville, Langley) voted over 60 percent for Kerry. Camano Island has a Republican lean and went for Bush with 52 percent of the vote in 2004, but is much less polarized than the rest of the county.
