The Ohio River Islands National Wildlife Refuge (ORINWR) is a National Wildlife Refuge (NWR) in non-contiguous sites consisting of islands along 392 miles (631 km) of the Ohio River, primarily (85% of acreage) in the U.S. state of West Virginia. There are also a couple of islands upstream in Beaver County, Pennsylvania and a couple downstream in Lewis County, Kentucky. Going downstream, the refuge is currently located in parts of these counties: Beaver, Brooke, Ohio, Marshall, Wetzel, Tyler, Pleasants, Wood, Jackson, Mason, and Lewis. All counties are in West Virginia, with the exceptions of Beaver, which is in Pennsylvania, and Lewis, which is in Kentucky. The ORINWR was established in 1990 and consists of 3,354 acres (13.57 km2) of land and underwater habitat on 22 islands and four mainland properties. Prior to its establishment, West Virginia was the only state of the United States without a NWR. (It now has two).
