This is a list of mayors and lord mayors of Newcastle and its predecessors, a local government area of New South Wales, Australia. The official title of Lord Mayors while holding office is: The Right Worshipful Lord Mayor of Newcastle.
First incorporated on 7 June 1859 as the "Municipality of Newcastle", the council became known as "The Borough of Newcastle" on 23 December 1867 following the enactment of The Municipalities Act of 1867, and on 1 April 1938 the "City of Greater Newcastle" was proclaimed. In recognition of Newcastle's role as NSW's second oldest and largest city, the council applied to have the title "Lord Mayor", which was granted in October 1947 by King George VI and applied in October 1948. This made Newcastle the first Australian city that was not a capital to receive such an honour. On 1 April 1949 the official title of the council became the "City of Newcastle".
