Särkkä is a small island outside Kaivopuisto park, northwest of Länsi-Mustasaari. Särkkä is part of Suomenlinna, and a part of the Suomenlinna fortress is also located here.

The island is 250m wide, and is located approx. 500m outside the mainland, outside the shore of Kaivopuisto park. Särkkä is nowadays being used by the yacht club Merenkävijät ry. There's also a summer restaurant, the restaurant Särkänlinna.
