Kenneth Whyld (6 March 1926 – 11 July 2003) was a British chess author and researcher, best known as the co-author (with David Hooper) of The Oxford Companion to Chess, the standard single-volume chess reference work in English.

Whyld was a strong amateur chess player, taking part in the British Chess Championship in 1956 and winning the county championship of Nottinghamshire. He subsequently made his living in information technology while writing books on chess and researching its history.

As well as The Oxford Companion to Chess, Whyld was the author of other reference works such as Chess: The Records (1986), an adjunct to the Guinness Book of Records and the comprehensive The Collected Games of Emanuel Lasker (1998). He also researched more esoteric subjects, resulting in works such as Alekhine Nazi Articles (2002) on articles in favour of the Nazi Party supposedly written by world chess champion Alexander Alekhine, and the bibliographies Fake Automata in Chess (1994) and Chess Columns: A List (2002).
