USS Saginaw Bay (CVE-82) was a Casablanca-class escort carrier of the United States Navy. It was named after Saginaw Bay, located within Kuiu Island. The bay was in turn named after USS Saginaw, a U.S. Navy sloop-of-war that spent 1868 and 1869 charting and exploring the Alaskan coast. Launched in January 1944, and commissioned in March, she served in support of the Mariana and Palau Islands campaign, the Philippines campaign, the Invasion of Iwo Jima, and the Battle of Okinawa. Postwar, she participated in Operation Magic Carpet. She was decommissioned in April 1946, when she was mothballed in the Atlantic Reserve Fleet. Ultimately, she was sold for scrapping in November 1959.

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.
