Carl Benjamin "Ben" Eielson (July 20, 1897 – November 9, 1929) was an American aviator, bush pilot and explorer.
When Eielson accompanied Wilkins on an Antarctic expedition later in 1928, they became the first men to fly over both polar regions of the world in the same year.
After his return from the Arctic flight, Eielson was asked to establish Alaskan Airways, a subsidiary of the Aviation Corporation of America.
In 1929, Eielson died alongside his mechanic Earl Borland in an air crash in Siberia while attempting to evacuate furs and personnel from the Nanuk, a cargo vessel trapped in the ice at North Cape (now Mys Shmidta).
The Carl Ben Eielson Memorial Building on the University of Alaska Fairbanks campus is named in his honor.
The Carl Ben Eielson House in Hatton, North Dakota is listed on the National Register of Historic Places.
