Abraham Duquesne-Guitton

Captain, later Admiral, Abraham de Bellebat (Belébat?) de Duquesne-Guitton, also spelled Duquesne-Guiton, (; 1648–1724) was a French naval commander.

In 1687, he sailed from the Cape of Good Hope in L'Oiseau, with a French Ambassador, Claude Céberet du Boullay, on board, to establish a French embassy in Ayutthaya.

He sighted Eendrachtsland on the Western Australian coast and sailed in close to shore near the Swan River on 4 August; this was France's first recorded contact with Australia. He wrote that it looked very attractive, and fully covered with green despite "the fact that we were in the middle of winter in this country".

His nephew Nicolas Gedeon de Voutron also sighted the western coast of Australia that year on another ship at the same latitude.
