Gula is a crater on Ganymede. It is a fresh crater with a distinctive central peak. It is about 40 km in diameter. A characteristic feature of both Gula and its southern neighbor Achelous, almost identical in size, is the "pedestal" − an outward-facing, gently sloped scarp that terminates the continuous ejecta blanket.

A crater is a circular depression likely created by an impact event. On Ganymede they are named after gods and heroes of ancient Fertile Crescent people.
