George Washburn (March 1, 1833 – February 15, 1915) was an American educator, Christian missionary, and second president of Robert College.

Washburn returned to the Andover Seminary to complete his education in 1862, and was ordained as a Congregational minister the next year.

Being appointed as a missionary for the American Board of Commissioners in Constantinople, he returned to the city, and subsequently became professor of philosophy in Robert College.

In 1876 he was instrumental, together with Dr. Albert Long, in sounding the first alarm and publicizing the Turkish massacres in Bulgaria.

He was offered the role of the United States ambassador to Turkey, but denied it due to a potential conflict of interest relating to his missionary work.
