Cronulla is a suburb of Sydney, in the state of New South Wales, Australia. Boasting numerous surf beaches and swimming spots, the suburb attracts both tourists and Greater Sydney residents. Cronulla is 26 kilometres south of the Sydney central business district, in the local government area of the Sutherland Shire.

Cronulla is on a peninsula framed by Botany Bay to the north, Bate Bay to the east, Port Hacking to the south, and Gunnamatta Bay to the west. The neighbouring suburb of Woolooware lies to the west of Cronulla, and Burraneer lies to the southwest. The Kurnell peninsula, the site of the first landfall on the eastern coastline made by Captain James Cook in 1770, is reached by driving northeast out of Cronulla on Captain Cook Drive.

Cronulla is derived from the Aboriginal word Kurranulla, meaning "place of the small pink seashell" in the dialect of the area's Indigenous inhabitants, the Gweagal, who were a clan of the Tharawal (or Dharawal) tribe. They inhabited the southern geographic areas of Sydney. The beaches were named by Surveyor Robert Dixon who surveyed here in 1827-28 and, by 1840, the main beach was still known as Karranulla. In July 1852 the schooner Venus was wrecked on the beach, which was referred to in newspaper reports as Cooranulla.

Matthew Flinders and George Bass explored and mapped the coastline and Port Hacking estuary in 1796 and the southernmost point of Cronulla is named Bass and Flinders Point in their honour. John Connell received a grant of 380 acres (1.5 km) in 1835. Thomas Holt (1811–88) owned most of the land that stretched from Sutherland to Cronulla in the 1860s. Holt built Sutherland House on the foreshore of Gwawley Bay in 1818, on the eastern side of Sylvania. In 1888 master mariner Captain Joseph Henry Rounce Spingall became the pioneering resident of Cronulla when, with his family, he constructed the two-storey 'Oriental Guest House' on land above where today's North Cronulla Hotel sits. The Depression of 1890 and a lack of reliable transport access from Sutherland saw "The Captain's" pub sold. The Cronulla area was subdivided in 1895 and land was offered for sale at 10 pounds per acre. In 1899, the government named the area Gunnamatta, which means sandy hills. On 26 February 1908, it was officially changed to Cronulla and Gunnamatta was used for the name of the bay, on the western side.

After the Illawarra railway line was built to Sutherland in 1885, the area became popular for picnics and swimming. Steam trams operated between Cronulla and Sutherland from 1911. Many regulars rented beach houses at Cronulla every year for school holidays. The Oriental Hotel was built by Captain Spingall in 1888, on the present site of apartments behind the North Cronulla Hotel. The Cecil Hotel was located on the foreshore of South Cronulla and the Ritz Café was popular with holiday-makers. The Cecil Apartments were built on the former site of this hotel. The steam trams were replaced by the Cronulla branch of the Illawarra railway line when it opened in 1939.

The post office opened in January 1891, known as Cronulla Beach, but closed in 1893. It reopened in 1907 and the name was officially changed to Cronulla in 1929.

The Cronulla School of Arts was established in 1904. The original wooden building was demolished and replaced by the current School of Arts building in November 1912 and is now one of the oldest buildings in Cronulla.

The first public school opened in 1910. In 1955, Cronulla Library opened. From the 1950s, many of the guest houses began being replaced by high rise flats. Even though it developed as a residential area, Cronulla remained popular with beachgoers and tourists. Several hotels, motels and serviced apartments operate today. The Cronulla Bicentennial Plaza opened in February 1989.

In 2005 the beachfront at Cronulla was the scene of widely publicised mob disturbances and violent confrontations. These incidents continued over a number of days and also spread to other areas in Sydney.
