Grass Island (Spanish: Isla Pasto) is a conspicuous island lying across the entrance to Stromness Harbour in Stromness Bay, South Georgia.

[1] On the 22 and 23 April 1982, after a British Special Boat Service team had been driven back by snow at Cumberland East Bay, as part of Operation Paraquet a Troop of the Special Air Service was landed on Grass Island from HMS Antrim, and set up an observation post in preparations for an attack on Argentine positions.

[2][3] In 2000, the island became rat-free after a team from New Zealand helped in an extermination.
