'''Ganymedes''' (gan'-ə-meed-əs; [[Grieks]]: ''Γανυμήδης''; ook '''Jupiter III''') is die grootste [[Natuurlike satelliet|maan]] van die [[planeet]] [[Jupiter (planeet)|Jupiter]], en ook die grootste maan in die [[sonnestelselSonnestelsel]]. GanymedesDit 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.]] ontdek is deur die [[China|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 Galileiaanse [[mane van Galilei]], [[Callisto (maan)|Callisto]], [[Europa (maan)|Europa]] en [[Io (maan)|Io]]. Ganymedes is die enigste maan van Jupiter wat 'n manlike naam het. Die maanDit is vernoemgenoem na [[Ganymedes (mitologie)|Ganymedes]], 'n goddelike held en [[Troje|Trojaanse]] prins, seun van [[Tros (mitologie)|Tros]] van Dardanië en [[Callirrhoe]], en 'n geliefde van [[Zeus]] in die [[Griekse mitologie]].
