Île Longue () is one of the Kerguelen Islands situated near to the south-east coast of Grande Terre, the principal island.
The highest point is a mountain named Pic d'Antoine, at 270 metres.
Since 1950 the island hosts about 3500 free range sheep bred in order to provide fresh meat to the Port-aux-Français settlement.Pierre Jullien, David Grangette, le berger des Kerguelen; article on Le Monde of January the 5th 2007; on-line abstract on
