Ganymedes (gan'-ə-meed-əs; Grieks: Γανυμήδης; ook Jupiter III) is die grootste maan van die planeet Jupiter en die grootste maan in die Sonnestelsel. Dit is groter as die planeet Mercurius, maar sy massa is net 50% van dié van Mercurius. Ganymedes is die enigste maan wat sonder 'n teleskoop sigbaar is, maar net in baie goeie en donker situasies.

Dis moontlik dat Ganymedes in 364 v.C. deur die Chinese sterrekundige Gan De ontdek is. Galileo Galilei kry egter gewoonlik die eer daarvoor; die sterrekundige het die maan se bestaan op 7 Januarie 1610 geregistreer, saam met die drie ander mane van Galilei, Callisto, Europa en Io. Ganymedes is die enigste maan van Jupiter wat 'n manlike naam het. Dit is genoem na Ganymedes, 'n goddelike held en Trojaanse prins, seun van Tros van Dardanië en Callirrhoe, en 'n geliefde van Zeus in die Griekse mitologie.
