Michel Bégon, known as Michel V Bégon or le Grand Bégon (25 December 1638 in Blois – 14 March 1710 in Rochefort) was a French ancien regime official. He was intendant de la marine at the port of Rochefort and intendant of the généralité of La Rochelle, as well as a passionate plant collector (he met the naturalist Charles Plumier in the Antilles, and Plumier later named the begonia after him).
