Machaut is a crater on Mercury.^[1] Its name was adopted by the International Astronomical Union in 1976. Machaut is named for the French composer and poet Guillaume de Machaut, who lived from 1300 to 1377.^[2]

Machaut is a volcanically modified crater. The floor was covered by volcanic deposits after the initial impact as shown by the partially submerged crater ("ghost crater") in the interior. ^[3]

Machaut is north of Snorri crater and west of Caruso and Boethius.
