Shellharbour City Centre is the central business district of the City of Shellharbour, located in the Illawarra region of New South Wales, Australia (not to be confused with the suburb, Shellharbour). Its name reflects its status as the commercial and administrative centre for the City of Shellharbour local government area, and is home to the Council Administration Centre (Lamerton House), Stockland Shellharbour shopping centre, cinemas and other retail shops.
The suburb was planned and developed to be the commercial heart of the local government area. The concept was developed in the 1970s by council in conjunction with the New South Wales Department of Planning. Planning and development has since been undertaken by council in partnership with Landcom, in an area of land that was formerly part of Blackbutt.
