The Alaskan Engineering Commission (AEC) was a U.S. Federal agency, sometimes known by its initials or by alternate spelling Alaska Engineering Commission. It was created by the Alaska Railroad Act in 1914, by U.S. President Woodrow Wilson, in order to arrange for construction of a railway system in Alaska. William C. Edes was named chairman, chief engineer Colonel Frederick Mears. In 1915, the AEC became part of the U.S. Department of the Interior. In 1923, after the railroad began operation and construction was complete, it became the Alaska Railroad Commission, later renamed to The Alaska Railroad.
Among other accomplishments, it designed and/or built a number of works listed on the U.S. National Register of Historic Places.
