Lilli Pilli is a small suburb in southern Sydney, in the state of New South Wales, Australia. Lilli Pilli is located 26 kilometres south of the Sydney central business district, in the local government area of the Sutherland Shire. There is also another Lilli Pilli in New South Wales (postcode 2536), located 12 kilometres south of Batemans Bay.

Lilli Pilli was named for the lilly pilly, the native myrtle that grew on the point. Thomas Holt (1811–88) owned most of the land that stretched from Sutherland to Cronulla, including land on the point. In 1840, parish maps also showed that 20 acres (8.1 ha) of land on the point were owned by Francis Mitchell.
