The Municipality of Mosman is a local government area on the Lower North Shore of Sydney, New South Wales, Australia.

The Mayor of the Mosman Council is Cr. Peter Abelson, a representative of the Serving Mosman independent political group.

A 2015 review of local government boundaries by the NSW Government Independent Pricing and Regulatory Tribunal recommended that the Municipality of Mosman merge with adjoining councils. The government considered two proposals. The first proposed a merger of Manly and Mosman Councils and parts of Warringah Council to form a new council with an area of 49 square kilometres (19 sq mi) and support a population of approximately 153,000. The alternative, proposed by Warringah Council on 23 February 2016, was for an amalgamation of the Pittwater, Manly and Warringah councils. As a consequence of Warringah's proposal, the New South Wales Minister for Local Government Paul Toole proposed that the North Sydney, Willoughby and Mosman Council be merged. The outcome of an independent review is expected by mid–2016.

In February 1997, the Government gazetted that they had assigned the suburb of Mosman as the only suburb in the Municipality of Mosman. However, Mosman Council decided that residents should continue to be allowed to use the traditional locality names if they wished.
