Iturup (Russian: Итуру́п and Остров Итуру́п, Ostrov Iturup; Ainu: エﾂﾟヲロプシㇼ, Etuworop-sir; Japanese: 択捉島, Etorofu-tō, historically also called Yetorup) is one of the Kuril Islands.
It was formerly known as Staten Island.
It is the largest and northernmost island in the southern Kurils, ownership of which is disputed by Japan and Russia.

The island was Japanese territory until the end of the Second World War in 1945, when Soviet forces took possession of all the Kurils and forced out Japanese residents.
The island is still claimed by Japan, which considers a site on Iturup to be its northernmost point.

Iturup is located near the southern end of the Kuril chain, between Kunashiri (19 km to the SW) and Urup (37 km to the NE).
The town of Kurilsk, administrative center of Kurilsky District, is located roughly midway along its western shore.

Iturup and Urup are separated by the Vries Strait, named after Dutch explorer Maarten Gerritsz Vries, the first recorded European to explore the area.
