Stronsay is an island in Orkney, Scotland. Its main village is Whitehall , home to a heritage centre . The island is now agricutural, but during the eighteenth and nineteenth centuries, kelp collection and herring curing employed up to 5,000 people.

Sights on the island include the Vat of Kirbuster natural arch and seabirds including arctic terns.

Ferries sail from Whitehall to Kirkwall on the Orkney Mainland, and planes fly there from the island's airstrip.
