Galway Marina sits within the Port of Galway, tucked into the docks area on the east side of the city near Lough Atalia.

Operated by the Galway Harbour Company, it offers 31 berths on a pontoon marina, with an additional four berths along a 60-metre pontoon walkway. Freshwater and electrical power are available at the pontoons.

The marina lies within the mouth of the River Corrib, entered from North Bay between Mutton Island and Hare Island, with the dockside approach framed by Nimmo's Pier to the west and Rinmore Point to the northeast.
