Conargo Shire Council is a local government area in the Riverina region in southern New South Wales, Australia. The Shire is the smallest local government area]] in New South Wales, using population as the measure.
Conargo Shire was established in 1907. In 2001 the former Windouran shire was absorbed into Conargo Shire. This amalgamation resulted in an additional 5,090 square kilometres (1,970 sq mi) and another 387 residents. It is divided into four wards, and contains six villages - Conargo, Blighty, Mayrung, Pretty Pine, Wanganella and Booroorban.
Before mergers in recent decades it was a common in New South Wales for rural shires to have their offices in an adjacent rural municipality (rural town). The only surviving case is Conargo Shire Council's offices in Deniliquin.
The Mayor of Conargo Shire Council is yet to be determined, following the 2012 local government elections.
