Sutherland Parish is one of the 57 parishes of Cumberland County, New South Wales, a cadastral unit for use on land titles. It was originally proclaimed as the parish of Southerland with an 'o', but was misspelled without it on the government gazette. It includes all of the Kurnell peninsula, with Botany Bay and the Georges River to the north; part of the Woronora River to the west; and Port Hacking to the south.
