Wyong Shire was a local government area located in the Central Coast region of New South Wales, Australia. The incorporation of the Wyong area dates back to 7 March 1906 when the entire area of the Brisbane Water Police District outside of the Town of Gosford was proclaimed as the Erina Shire. From 1 January 1947, local government in the Central Coast region was reorganised, creating Gosford Shire and Wyong Shire, which comprised Erina Shire north and east of Kulnura, Central Mangrove and Lisarow.
