John Lord (September 10, 1810 – December 15, 1894) was an American historian and lecturer.

Born September 10, 1810 in Portsmouth, New Hampshire, he graduated from Dartmouth College in 1833 and then entered the Andover Theological Seminary, where in his second year he wrote a series of lectures on the Dark Ages, which he delivered the next fall during a tour through northern New York. After graduating at Andover he became an agent for the American Peace Society. Though not ordained to the ministry, he was called to a Congregational Church at New Marlborough, Massachusetts, and then to one at Stockbridge, Massachusetts.

In 1840 he gave up his pastoral duties to become a public lecturer and spend time on literary activities. In 1843-46, he was in England giving lectures on the Middle Ages, and on his return to the United States continued to lecture for many years in the principal towns and cities, giving over 6,000 lectures in all. In 1864, he received his LL.D. from the University of the City of New York. From 1866 to 1876, he was lecturer on history at Dartmouth College.

Lord died December 15, 1894, in Stamford, Connecticut.
