Ellamar Mountain is a prominent mountain summit located in the Chugach Mountains, in the U.S. state of Alaska. It is situated northwest of Cordova, southwest of Valdez, and north of Tatitlek, on land managed by Chugach National Forest. It is approximately northeast of Bligh Reef, the location of the 1989 "Exxon Valdez" oil spill. The mountain's local name was taken from the copper mining camp of "Ellamar" at the southwest base of the mountain. In turn, Ellamar is a portmanteau of "Ella" and "Margaret". When a post office was established for this new mining camp, C. L. Wayland, the first Postal Inspector for the Territory of Alaska and parts of the Pacific Northwest, coined Ellamar from the names of his wife, Ella, and daughter, Margaret. Precipitation runoff from the mountain drains into Prince William Sound.
