USS Ommaney Bay (CVE–79) was a Casablanca-class escort carrier of the United States Navy, which served during World War II. It was named after Ommaney Bay, located at the south end of Baranof Island, Alaska. Launched in late 1943 and commissioned in early 1944, the ship took part in the Mariana and Palau Islands campaign followed by several battles during the Philippines campaign in 1944 and early 1945. She was heavily damaged in a kamikaze attack and subsequently scuttled on 4 January 1945, with the loss of 95 men, including two men on board the destroyer escort Eichenberger who were killed by flying debris. She earned 2 battle stars whilst in service. In 2023, the Navy History and Heritage command announced that the wreck was located by "a combination of underwater survey and video information provided by Sea Scan Survey and DPT Scuba, two Australian diving firms, to positively identify the wreck."

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.
