The Cape St. Elias Light is a lighthouse on Kayak Island in Alaska.

Cape St. Elias Lighthouse was added to the National Register of Historic Places in 1975.

It is now being leased by the Cape St. Elias Lightkeepers Association, a non-profit organization dedicated to preserving, restoring and sharing the lighthouse.

This lighthouse "proved to be an indispensable navigational aid along the shipping lanes from the contiguous American states and Southeastern Alaska to Cordova, Valdez, Seward, and Anchorage."

Those ports could be notified of ships arriving, by station keeper radio that also was installed in 1916.
