List Description

The list of highest islands in the United States is utterly dominated by peaks in Alaska and Hawaii. The highest island peak in the 48 contiguous states is Devils Peak in California's Channel Islands (2450 feet), and it would rank somewhere around #52 on the nationwide list. Older versions of this list on this site had incomplete island information about the large number of high island peaks in Alaska, so the list was changed to a 4000-foot cutoff in early 2010 to focus on the true highest American islands.

This list does not include the high points of lake islands, or of islands part of U.S. dependencies such as Puerto Rico, Guam, and others.
