Clontarf (Irish: Cluain Tarbh, meaning "meadow of the bull") is a suburb of northern Sydney, in the state of New South Wales, Australia. Clontarf is located 13 kilometres north-east of the Sydney central business district in the local government area of Northern Beaches Council, in the Northern Beaches region.
Clontarf's landmarks are Clontarf Beach, Sandy Bay, Castle Rock and Grotto Point.
Clontarf is named after the Clontarf district in Dublin, Ireland.
The son of Queen Victoria, Prince Alfred, Duke of Edinburgh, visited Clontarf in 1868 where he was shot in the back by an Irishman, Henry James O'Farrell. Alfred was saved because the bullet struck him at a point where his India-rubber braces, holding his trousers up, crossed over. The bullet was deflected around his rib-cage and did no major harm.
In February 2021 Transport for NSW advised that one of the series 2 Emerald-class ferries to commence service on the Manly ferry service, around the middle of 2021, would be named Clontarf after Clontarf Beach.[1]
