John L. Langdon (December 24, 1944 – December 31, 2016) was a British-born Canadian economic and social historian of medieval England.

Career
Langdon undertook his doctoral work at the University of Birmingham, UK under the supervision of Christopher Dyer. He worked at the University of Alberta, Canada (1984–2010), being appointed assistant professor of British medieval history in 1984. Beloved by his students, he ranked 4.6 out of 5 on RateMyProfessors.com.

He is best known for his contributions on medieval English technology, chiefly two monographs: Horses, Oxen and Technological Innovation: The Use of Draught Animals in English Farming from 1066–1500 (Cambridge University Press, 1986) and Mills in the Medieval Economy: England 1300–1540 (Oxford University Press, 2004).

He also co-edited a number of essay collections. With Grenville G. Astill, he edited Medieval Farming and Technology: The Impact of Agricultural Change in Northwest Europe (Brill, 1997). With Richard Goddard and Miriam Müller he edited a festschrift for Professor Christopher Dyer: Survival and Discord in Medieval Society, Essays in Honour of Christopher Dyer. Together with Maryanne Kowaleski and Phillipp R. Schofield he edited a festschrift for Professor Bruce Campbell: Peasants and Lords in the Medieval English Economy: Essays in Honour of Bruce M.S. Campbell.

His research continued into his retirement, his last research project, "A war over water: The 1531 English Statue of Sewers and its impact upon local politics, economies and environments" commencing in 2013.
