Barden Ridge is a suburb in southern Sydney, in the state of New South Wales, Australia.

Barden Ridge is located 29 kilometres south of the Sydney central business district in the local government area of the Sutherland Shire.

'The Needles' is a body of water (ria) on the Woronora River, on one of the original roads west from Helensburgh.

Barden Ridge has shifted from a remote bushland area to an exclusive suburb that now contains all the necessary amenities that have established a strong community.

A new section of the Bypass was constructed and passes by Barden Ridge improving the current access to the area and Heathcote Road (to the south).

[4] There is also another Baseball/AFL oval and a park directly adjacent to Lucas Heights Community School, which itself has two sporting fields and three basketball courts.

Barden Ridge has a long Liberal Party history, which only changed in recent memory during the stalled construction of the Woronora Bridge.

In State Government, it comes under the seat of Holsworthy, which is currently held by the Liberal MP, Tina Ayyad.
