Groote Eylandt is the largest island in the Gulf of Carpentaria and the fourth largest island in Australia. It was named by the explorer Abel Tasman in 1644 and is Dutch for "Large Island" in archaic spelling. The modern Dutch spelling is Groot Eiland.

The Gulf of Carpentaria is a sea off the northern coast of Australia. It is enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea, which separates Australia and New Guinea. The northern boundary is generally defined as a line from Slade Point, Queensland in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory in the west.
