South Cumberland Islands is a national park in Queensland, Australia, 831 km northwest of Brisbane.

Scawfell Island (located at 20°52'S., 149°37'E., 60 kilometres (37 mi) off the cost of Queensland, north-east of Mackay) is officially regarded as the beginning of the Whitsunday group.

It was originally part of the Cumberland Isles Group identified by Captain James Cook in 1770, but was not named.

The name of the island originates from England's second highest peak, Scafell, in Cumbria, which was then spelt "Scawfell".

It is the largest national park island in the South Cumberland group, and is uninhabited.
