Manly is a beach-side suburb of northern Sydney, in the state of New South Wales, Australia. It is 17 kilometres (11 mi) north-east of the Sydney central business district and is currently one of the three administrative centres of the local government area of Northern Beaches Council. Manly has a long-standing reputation as a tourist destination, owing to its attractive setting on the Pacific Ocean and easy accessibility by ferry.

Manly was named by Captain Arthur Phillip for the Indigenous people living there, stating that "their confidence and manly behaviour made me give the name of Manly Cove to this place". These men were of the Kay-ye-my clan (of the Dharug-speaking Gayemaygal people). While scouting for fresh water in the area, Phillip encountered members of the clan, and after a kidnapping he was speared in the shoulder by one of the clan as a punishment ritual; the progressively-minded Phillip ordered his men not to retaliate. In Capt. Tench's words,

The Aboriginal men were feasting on a whale at Manly Cove and were seen by Captain Nepean, Mr White, Nanbaree & a party of men who had travelled to Manly Cove to walk to Broken Bay. Bennelong and Colebee spoke to them and Bennelong asked for Governor Phillip. Captain Nepean sent the Boatswain back to Governor Phillip at South Head. The Aboriginal men cut large chunks of whale off and put them in the boat for Governor Phillip. The military party then proceeded on their walk to Broken Bay. When Governor Phillip's party arrived to see the Aboriginal men they held friendly conversation with Bennelong and Colebee for over half an hour. Later an older Aboriginal man appeared with a spear. Captain Tench remarked that he was seemingly a stranger and little acquainted with Bennelong and Colebee. The Governor moved towards this man and the man became agitated. Governor Phillip threw down his dirk to appease the man crying out confidently. The spear was thrown and Governor Phillip was hit in the shoulder. All was in confusion, there were calls to bring the muskets, Bennelong and Colebee disappeared and Governor Phillip could not make it to the ship because of the length of spear sticking from his shoulder and dragging on the ground. The muskets were brought to shore but only one would fire. The spear was finally broken and all hastened to Port Jackson.

Manly had been envisaged as a seaside resort by Henry Gilbert Smith in the 1850s. In 1853, Smith acquired two large parcels of land (which had been granted to John Thompson in 1842 and John Crane Parker in 1837).

Initially John had chartered a paddle steamer to Manly and other vessels visited on an ad hoc "excursion" basis. Smith built a wharf on the harbour-side of Manly, which was completed in October 1855 and eventually acquired an interest in steamers himself. as part of developing more regular services to Manly to assist his sub-division property sales.

By 1873, Smith had sold the lease to the wharf and his share of the steamers to the operators of the ferries and eventually ownership passed to the once famous Port Jackson & Manly Steamship Company. It was the Port Jackson & Manly Steamship Company which coined the expression about Manly being "Seven miles from Sydney and a thousand miles from care" to promote its ferry service. The Port Jackson & Manly Steamship Company played an important part in Manly's development. It built several attractions including a large ocean pool and bathing pavilion, the Manly Fun Pier. In 1972 the company was sold to Brambles and in 1974 to the Government of New South Wales and it is now part of Sydney Ferries.

In March 1885, as the New South Wales Contingent was about to depart for the Sudan, a letter was addressed to Premier William Bede Dalley containing a cheque for £25 for the Patriotic Fund "with my best wishes from a little boy at Manly". It was Australia's first overseas military adventure, and the "Little Boy from Manly" became a symbol either of patriotism or, among opponents of the adventure, of mindless chauvinism. especially due to a cartoon by Livingston Hopkins of The Bulletin.

In 1896, the first film ever made in Australia was Marius Sestier's Passengers Alighting from Ferry Brighton at Manly. The film, consisting of footage of the PS Brighton arriving at the wharf, premiered at the Salon Lumière on Pitt St (Australia's first cinema) on 27 October 1896. No copy is known to have survived.

During the 19th and early 20th centuries, Manly was one of Australia's most popular seaside holiday resorts. Manly Beach is said to be the place where the restriction on daylight sea bathing was first challenged in Australia. In October 1902 William Gocher, clad in a neck to knee costume, swam at midday after announcing his intention to do so in the newspaper he had established (Manly and North Sydney News). After being ignored by authorities and being publicly critical of them, he swam again and was escorted from the water by the police, although no charges were laid. In November 1903, Manly Council resolved to allow all-day bathing provided a neck to knee swimming costume was worn. During the first official bathing season in 1903, 17 people drowned on Manly Beach. A year later a surf club was formed on the beach to safeguard the public. While there is debate about which club is the oldest, Manly Life Saving Club is one of the world's first surf life saving clubs.

In 1934, George Robey, a resident and original Anzac founded the Air Mindedness Development League which was later renamed the "Australian Air League" at Manly. There has been a continuously running squadron in Manly since. In 1937 Manly Town Hall was opened.

In 1973, residents in the Eastern Hill section of Manly requested that the NSW Builders Labourers Federation place a green ban on the construction of two large tower blocks by LJ Hooker. The BLF agreed to do so and asked them to draw up a community plan for the area's future.

Manly is most notable for its beaches, which are popular tourist destinations. Manly features a long stretch of sand on the ocean side, that runs from Queenscliff through North Steyne to South Steyne. This is followed by rock pools and sandy beaches called Fairy Bower and Shelly Beach. There are also a number of beaches on the harbour side of the peninsula being Collins Beach, Store Beach, Little Manly, East Manly Cove, West Manly Cove, Delwood Beach and Fairlight Beach. Norfolk Island pine trees are symbolic of Manly and are a prominent feature of both the ocean and harbour beaches.

On 10 March 2012, the 4-kilometre (2.5 mi) stretch between Freshwater Beach and Shelly Beach was declared the "Manly -Freshwater World Surfing Reserve". The Reserve was dedicated in a ceremony in Manly Beach by world surfing champion Kelly Slater accompanied by the Governor of New South Wales, Marie Bashir.

The commercial Manly is centred around The Corso, which runs from the harbour side at Manly wharf to the ocean side at Manly Beach. Part of The Corso is a mall which allows outdoor dining for cafes and restaurants. The commercial area extends to surrounding streets with more cafes and restaurants concentrated along the ocean and harbour shores.

Baz Luhrmann's The Great Gatsby (2013) was filmed in Sydney, primarily in Manly and Balmain. St Patrick's Seminary was used as Jay Gatsby's mansion–palm trees at the building's exterior had to be digitally removed in post-production to create a realistic depiction of the Eastern United States (specifically Long Island), where the novel and film are set.

According to the 2021 census, there were 16,296 residents in Manly. 55.2% of residents were born in Australia.

Transport services to Manly include a ferry service from Manly wharf, and CDC NSW and Keolis Downer Northern Beaches bus services to the city and other suburbs. The Manly Ferry journey takes 30 minutes and allows for scenic views of Sydney Harbour, surrounding national parks and Sydney icons including the Harbour Bridge and Opera House. The ferry service once advertised Manly as "seven miles from Sydney, and a thousand miles from care".

A privately owned and operated Manly Fast Ferry operates between Manly and Circular Quay, offering transport in a claimed trip time of 18 minutes, but this excludes unloading time. This replaced a similar but superior high speed operation that was run with a 15 minute (later 12 minute) trip hydrofoil service from 1964 until 1992 and then a 15 minute trip JetCat service which was used to replace the hydrofoils from 1990, but was withdrawn by the NSW Government in late December 2008.

The relaxed lifestyle, beaches and proximity to Sydney city have led to Manly's real estate prices being amongst the highest in Australia. The adjoining suburb of Seaforth, which is now also part of Northern Beaches Council, has been ranked as the 25th richest suburb in Australia.

The former Catholic seminary at St Patrick's Estate, Darley Road, now houses The International College of Management, Sydney (ICMS) a management college, specializing in business, tourism, hospitality, events, property, sports and marketing retail management. It is affiliated with Macquarie University, which attracts international students from many countries. As well as being an educational hub, many spectacular weddings have been held here, including Nicole Kidman and Keith Urban. The original seminary was designed by Hennessy and Sheerin and built in 1885. It was conceived by Archbishop Vaughan and is now listed on the Register of the National Estate.

On the other side of Darley Road is the Archbishop's House, also known as the Cardinal's Palace. This building was also designed by Sheerin and Hennessy and built in the 1880s. It was originally conceived as part of St Patrick's Seminary and is a good example of the Victorian Gothic Revival style. It too is listed on the Register of the National Estate.

Another notable landmark is the Presbyterian Church in Raglan Street. It was designed by John Sulman in the Romanesque style and built in 1892. It is listed on the Register of the National Estate.
