The New South Wales State Heritage Register, also known as NSW State Heritage Register, is a heritage list of places in the state of New South Wales, Australia, that are protected by New South Wales legislation, generally covered by the Heritage Act 1977 and its 2010 amendments. The register is administered by the Heritage Council of NSW via Heritage NSW, a division of the Government of New South Wales Department of Planning and Environment.
The register was created in 1999 and includes items protected by heritage schedules that relate to the State, and to regional and to local environmental plans. As a result, the register contains over 20,000 statutory-listed items in either public or private ownership of historical, cultural, and architectural value. Of those items listed, approximately 1,785 items are listed as significant items for the whole of New South Wales; with the remaining items of local or regional heritage value. The items include buildings, objects, monuments, Aboriginal places, gardens, bridges, landscapes, archaeological sites, shipwrecks, relics, bridges, streets, industrial structures and conservation precincts.
