Neutral Bay is a suburb on the Lower North Shore of Sydney, New South Wales, Australia. Neutral Bay is around 1.5 kilometres north of the Sydney central business district, in the local government area of North Sydney Council.

Neutral Bay takes its name from the bay on Sydney Harbour. Kurraba Point, formerly a locality in Neutral Bay, was declared a separate suburb in 2010, sharing the postcode 2089. Surrounding suburbs include North Sydney, Cammeray, Milsons Point, Cremorne and Cremorne Point.

The name "Neutral Bay" originates from the time of the early colonial period of Australia, where different bays of Sydney harbour were zoned for different incoming vessels. This bay was where all foreign vessels would dock, hence the name neutral.

The Aboriginal name for the area was 'Wirra-birra'. In 1789, soon after the arrival of the First Fleet in Sydney, Governor Arthur Phillip declared this bay a neutral harbour where foreign ships could anchor and take on water and supplies. Neutral Bay was far enough away from Sydney Cove to discourage convicts from escaping on these vessels and to keep possible enemy ships at a distance from the main settlement.

By the beginning of the 20th century, Neutral Bay and Cremorne were developing as "alternative society suburbs", populated by the kind of people who were attracted to the Arts and Crafts architectural style that was in vogue at the time. This style was an attempt to get away from mass production and give homes the "human touch". Notable examples soon appeared in the area. Brent Knowle, in Shellcove Road (now part of Kurraba Point), was designed by Bertrand James Waterhouse and built in 1914. It influenced home design in the area for at least the next fifteen years and has a state heritage listing.

A different style was used for The Cobbles (now in Kurraba Point), also in Shellcove Road. Designed by Peddle and Thorp and built in 1918, it made great use of natural stones and pebbles to achieve the desired look. It is an Australian interpretation of the California Bungalow style and has a state heritage listing. The Gables, in Spruson Street, was another Waterhouse design and was built in 1920. It was influenced by the "shingle style" which was brought to Sydney by Horbury Hunt, and featured prominent gables and extensive use of shingles. More Waterhouse designs appeared in Shellcove Road in the vicinity of The Cobbles and Brent Knowle (now in Kurraba Point). An outstanding example is Ailsa (now in Kurraba Point), which was designed by Waterhouse for Captain Robert Craig and built in 1908. It has a state heritage listing. Along with Keynsham (now in Kurraba Point), St Anne's (now in Kurraba Point), and Gundimaine House (now in Kurraba Point), these homes form a significant heritage group and have a state heritage listing.

Neutral Bay was also the home of the English-born children's author and painter May Gibbs, who lived for a time in Derry, a two-storey Federation home in Phillips Street. Afterwards, she moved to the home Nutcote in nearby Kurraba Point.

Neutral Bay was the location of the Royal Australian Navy's Submarine Service HMAS Platypus (naval base) between 18 August 1967 and 29 March 1999. It was home to the HMA Oberon submarines, with the first HMAS Oxley arriving at the site on the same day as the commissioning. During World War 2 the site was converted for use as the RAN Torpedo Maintenance Establishment (RANTME).

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

• 2 Hayes Street: Hastings (Neutral Bay)
• Yeo Street: St John's Uniting Church and Pipe Organ

The main shopping district of Neutral Bay, known as Neutral Bay Junction, is along Military Road, which is the main road that runs through Neutral Bay, Cremorne and Mosman. It features many shops, restaurants and cafes. The Big Bear shopping centre is a shopping mall that features a supermarket and grocery shops. Keolis Downer Northern Beaches' North Sydney Bus Depot is located behind the Big Bear.

The Oaks Hotel is a well-known and popular venue located on the corner of Military Road and Ben Boyd Road. It has been a popular meeting place in Sydney since 1885. The Oaks Hotel features a number of restaurants, bars, function rooms and a beer garden with the main focal point an old oak tree.

At the 2016 census, 39.2% of employed people travelled to work on public transport and 36.4% by car (either as driver or as passenger).

The Neutral Bay wharf sits at the end of Hayes Street and it is serviced by both public Neutral Bay ferry services and private ferries.

The Warringah Freeway runs along the western border of Neutral Bay, providing links south to the Sydney CBD and north to Chatswood. Military Road has been a prominent local electoral issue, due to issues relating to the heavy traffic congestion on the road.
