Major Sir Edgar Mayne Keatinge CBE (3 February 1905 – 7 August 1998) was an English farmer, soldier and Conservative Party politician. He is best known for having served as the Member of Parliament (MP) for Bury St Edmunds from 1944 to 1945, after a high-profile by-election. He disliked the name Edgar and preferred to introduce himself as "Mike". An obituarist describes him as "a simple and loyal man who had, for a brief period, endured a significant role in national life; and discharged his duty with honour".
