Mona Vale is a suburb of Sydney, in the state of New South Wales, Australia. It is located 28 kilometres north of the Sydney central business district, in an area known as the Northern Beaches. Formerly the administrative centre of Pittwater Council, it is now located in the local government area of Northern Beaches Council.^[2] The traditional custodians of the area are the Garigal people. It is often colloquially referred to as "Mona".

The area was known as "Bongin Bongin" by Aboriginal Peoples.^[3][4] The initial land grants in the district of Pittwater were not made until April 1813, and those sections which now comprise Mona Vale, first surveyed in May 1814, were granted to Robert Campbell (1769-1846). These were originally part of 700 acres (2.8 km²) that extended northwards from Mona Vale to the end of Newport beach.^[5] Local lore suggests the name Mona Vale was chosen by Campbell in remembrance of a town bearing the same name in Scotland, however the exact location of this place remains a mystery.

Pittwater Council, after the council chambers moved from Warriewood. Since then, Pittwater Council has been amalgamated with Warringah and Manly to form the Northern Beaches Council.

Mona Vale has two primary schools and a high school, an RSL club, a park, public library, golf course, hospital, a world class skate park, a bus depot, three supermarkets, and a variety of shops and businesses. There are also a number of pathways and walking tracks around the area.^[6]

Mona Vale Hospital is the local public healthcare facility, which has been undergoing a process of re-development since the opening of the newly built Northern Beaches Hospital.^[7]

Mona Vale has a shallow beach (formerly known as "Bongin Bongin" Beach)^[4] which has a children's and lap pool at its northern end, with the main beach adjoining the golf course and a number of parks and reserves. There is a second beach north of this which is known as "The Basin" with a concentrated wave which, since the early 2000s, has been known as "Whomp" which is popular with body boarders. Mona Vale is a popular beach for surfing with beach breaks including "Main", "Suck Rock" which holds the annual competition known as KOTR or king of the rock, and "Rip Bowl".
