USS Sitkoh Bay (CVE-86) was the thirty-second of fifty Casablanca-class escort carriers built for the United States Navy during World War II. She was named after Sitkoh Bay, located within Chichagof Island, of the Territory of Alaska. The ship was launched in February 1944, commissioned in March, and served as a replenishment and transport carrier throughout the Philippines campaign, the Invasion of Iwo Jima and the Battle of Okinawa. She was decommissioned in November 1946, when she was mothballed in the Atlantic Reserve Fleet. With the outbreak of the Korean War, however, she was called back to service, continuing to serve as a transport and utility carrier with the Military Sealift Command until 1954, when she was once again decommissioned, and mothballed in the Pacific Reserve Fleet. Ultimately, she was broken up in January 1961.

The Casablanca-class escort carrier was a series of escort carriers constructed for the United States Navy during World War II. They are the most numerous class of aircraft carriers ever built. Fifty were laid down, launched and commissioned within the space of less than two years – 3 November 1942 through to 8 July 1944. Despite their numbers, and the preservation of more famous and larger carriers as museums, none of these modest ships survive today. Five were lost to enemy action during World War II and the remainder were scrapped.
