Rutland Island is an island located across the Macpherson Strait from Port Blair, the capital of the Indian union territory of Andaman and Nicobar Islands on South Andaman Island. As one of the Andaman Islands, Rutland I forms the southernmost main island of the closely-situated Great Andaman archipelago. The island spans an area of approximately 109.3 km², and has a coastline measuring some 60 km.
It is rich in marine life with the shallow waters near the island having a good representation of smaller fish and coral. The island also offers an ideal base for training open water divers. The vegetation of Rutland Island is similar to that of North Sentinel Island with dry sandy soils. Although hilly, the island is overgrown with fairly open jungle and brush.
