Wollondilly Shire is a periurban local government area that is located on the far southwest fringe of the Greater Sydney area in New South Wales, Australia. The local government area is part of the Macarthur and Blue Mountains regions. The Wollondilly Shire is seen as the transition between Regional NSW and the Greater Sydney area, as it meets the Sydney urban area to rural areas. Wollondilly Shire was created by proclamation in the NSW Government Gazette on 7 March 1906, following the passing of the Local Government (Shires) Act 1905, and amalgamated with the Municipality of Picton on 1 May 1940.

Wollondilly Shire is named after the Wollondilly River. The area is traversed by the Hume Highway and the Southern Highlands railway line. Wollondilly Shire contains several small towns and villages broken up by farms and sandstone gorges. To its west is wilderness and includes the Nattai Wilderness and the Burragorang Valley. The majority of the Shire is either national park or forms part of the water catchment for Sydney's water supply. The Shire provides 97% of Sydney's water supply with the Warragamba Dam holding 80% of that.
