Ellsworth Price Bertholf (7 April 1866 – 11 November 1921) was a Congressional Gold Medal recipient who later served as the fourth Captain-Commandant of the United States Revenue Cutter Service and because of the change in the name of the agency, the fourth Commandant of the United States Coast Guard. His leadership during his tenure as Commandant was critical to the Coast Guard's survival at a time when outside agencies wanted to either take it over or split its missions up among several agencies.
