Scotland Island is an island in the north of Sydney, in the state of New South Wales, Australia. Church Point, Scotland Island's major mainland service locality, is located 32 kilometres north of the Sydney central business district, in the local government area of Northern Beaches Council.
Scotland Island is located in Pittwater, off Church Point. The island is approximately 1 km in diameter and its highest point is about 120 metres above sea level. To the east is the suburb of Newport, west is Ku-ring-gai Chase National Park, and south are the suburbs of Church Point and Bayview.
Around 18,000 years ago Scotland Island was a hill in a river valley. Following the last ice age, sea levels rose, flooding the valley, forming Pittwater and creating the island. There are many small beaches, consisting mainly of mud, mangroves and rocks. There are no rivers or cliffs, but some small caves towards the top of the island. The top of the island is sandstone and the lower part consists of shale.
