Charles Harding Firth (March 16, 1857 _ February 19, 1936) was a British historian.

Born in Sheffield, he was educated at Clifton College and at Balliol College, Oxford. At university he took the Stanhope prize for an essay on Richard Colley Wesley, Marquess Wellesley in 1877, became lecturer at Pembroke College in 1887, and fellow of All Souls College in 1901. He was Ford's lecturer in English history in 1900, and became regius professor of modern history at Oxford in succession to Frederick York Powell in 1904. Firth's historical work was almost entirely confined to English history during the time of the English Civil War and the Commonwealth; and although he is somewhat overshadowed by SR Gardiner, who wrote about the same period, his books were highly regarded.
