USS Makassar Strait (CVE–91) was a Casablanca class escort carrier of the United States Navy. She was named after Makassar Strait, the strait between Kalimantan and Sulawesi, Indonesia.
She was originally classified AVG-91, reclassified ACV-91 on 20 August 1942, and reclassified CVE-91 on 15 July 1943; originally named Ulitaka Bay and renamed Makassar Strait 6 November 1943; laid down by Kaiser Co., Inc., Vancouver, Washington, under Maritime Commission contract 29 December 1943; launched 22 March 1944; sponsored by Mrs. Truman J.

After shakedown along the United States West Coast, Makassar Strait departed San Diego, California, on 6 June 1944 and steamed via Pearl Harbor, Hawaii, to the Marshall Islands carrying replacement aircraft and passengers; from there, she transported military casualties to Pearl Harbor and San Diego, where she arrived on 13 July 1944. During much of the next two months she trained aircraft carrier pilots off Southern California. Between 25 September and 15 October 1944, she ferried 129 planes to Hawaii and to Manus Island in the Admiralty Islands. After returning to Pearl Harbor on 26 October 1944 with 70 damaged Grumman F4F Wildcats on board, she resumed pilot training operations out of Pearl Harbor.
