USS Chukawan (AO-100) was a Cimarron-class fleet oiler constructed for the U.S. Navy in the closing days of World War II.

Chukawan (AO-100) was launched 28 August 1945 by Bethlehem Steel Co., Sparrows Point, Maryland; sponsored by Miss M. McCrea; commissioned 22 January 1946 and reported to the Atlantic Fleet.

The first came in November 1956, upon the outbreak of the Suez Crisis, when she sailed from Norfolk on short notice with a carrier task force assigned to stand by in the eastern Atlantic should American strength in the Mediterranean need enhancement.

Her second dramatic incident occurred through her service to 6th Fleet ships during the 1958 Lebanon crisis, when such support as hers made possible the landing of U.S. Marines on the shortest possible notice.
