Lavender Bay is a harbourside suburb on the lower North Shore of Sydney, New South Wales, Australia. Lavender Bay is located three kilometres north of the Sydney central business district, in the local government area of North Sydney Council.

The suburb takes its name from Lavender Bay, a natural feature of Port Jackson (Sydney Harbour) immediately west of the Sydney Harbour Bridge. It lies between Milsons Point and McMahons Point. The suburb North Sydney is located, to the north. Lavender Bay is a residential suburb with expansive views of Sydney Harbour.

Lavender Bay was named after the Boatswain (bosun), George Lavender, from the prison hulk "Phoenix", which was moored there for many years. The bay is dual-named Gooweebahree, (also sometimes written as Quiberee) in the Dharug language of the local inhabitants, the Cammeraygal people of the Eora nation. The colonists also called it Hulk Bay and sometimes Phoenix Bay. George Lavender lived on 14 acres (57,000 m) adjacent to the property of Billy Blue. On 30 May 1915 Lavender Bay railway station was opened to take the place of Milsons Point railway station. This only lasted for seven weeks, as passengers refused to alight here and demanded that trains stop at Milsons Point. During the Sydney Harbour Bridge construction, Lavender Bay station was the terminus of the North Shore railway line. The area is now used to stable Sydney Trains rolling stock.

Lavender Bay has a number of heritage-listed sites, including:
