George Macaulay Trevelyan OM CBE FRS FBA (16 February 1876 – 21 July 1962) was an English historian and academic. He was a Fellow of Trinity College, Cambridge, from 1898 to 1903. He then spent more than twenty years as a full-time author. He returned to the University of Cambridge and was Regius Professor of History from 1927 to 1943. He served as Master of Trinity College from 1940 to 1951. In retirement, he was Chancellor of Durham University.
Trevelyan was the third son of Sir George Otto Trevelyan, 2nd Baronet, and great-nephew of Thomas Babington Macaulay. He espoused Macaulay's staunch liberal Whig principles in accessible works of literate narrative unfettered by scholarly neutrality, his style becoming old-fashioned in the course of his long and productive career. The historian E. H. Carr considered Trevelyan to be one of the last historians of the Whig tradition.
