Mount Abdallah is a prominent 6,210-foot mountain summit located in the Alsek Ranges of the Saint Elias Mountains, in southeast Alaska. The mountain is situated in Glacier Bay National Park and Preserve, as the highest point between Tarr Inlet and Rendu Inlet, 93 mi northwest of Juneau, and 10.5 mi southeast of Mount Barnard, which is the nearest higher peak. Although modest in elevation, relief is significant since the mountain rises up from tidewater in less than three miles.
