The Division of Bradfield is an Australian electoral division in the state of New South Wales.

Bradfield was created in the 1949 expansion of Parliament, and was named in honour of John Bradfield,^[1] the designer and builder of the Sydney Harbour Bridge. Its first member was Billy Hughes, a former Prime Minister of Australia and the last serving member of the first federal Parliament. The bulk of the seat was carved out of North Sydney, which Hughes represented from 1923 to 1949. After Hughes, its best-known member was Brendan Nelson, a minister in the third and fourth Howard governments and the federal Leader of the Opposition from 2007 to 2008. The current Member for Bradfield, since the 2009 Bradfield by-election, is Paul Fletcher, a member of the Liberal Party of Australia.

Located in the traditional Liberal stronghold of Sydney's North Shore, Bradfield has been in Liberal hands for its entire existence, and for most of that time has been reckoned as a very safe Liberal seat.^[2] Most of the territory covered by the seat has been represented by centre-right MPs since Federation.

While Labor historically runs dead in the North Shore, Bradfield is particularly hostile territory for Labor; the party has never come anywhere close to winning the seat. The Liberal hold on the seat has only been even remotely threatened twice. At a 1952 by-election triggered by Hughes’ death, the Liberals were held to 58 percent of the two-party vote. Even then, the Liberals still won more than enough primary votes to retain the seat without the need for preferences.

In the 2022 federal election, Voices of Bradfield-endorsed independent candidate Nicolette Boele slashed the Liberal margin in the seat from 16.56% to 4.23%, turning Bradfield into a marginal seat on a two-candidate preferred basis for the first time in its history, amid the collapse of Liberal support in the North Shore. The swing against the Liberals was enough to drop the Liberal margin in a "traditional" two-party contest with Labor to 56 percent, the first time the seat has been marginal against Labor. The Liberal primary vote plummeted to 45.05%, the first time the Liberal Party received less than 50% of the primary vote in Bradfield. The Liberals lost 15.28% of their primary vote, the largest swing in the country.

Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned.^[3]

The electorate is located in the upper North Shore and covers an area of approximately 101 km², covering the suburbs Castle Cove, East Killara, East Lindfield, Gordon, Killara, Lindfield, North Turramurra, North Wahroonga, Pymble, Roseville, Roseville Chase, South Turramurra, St Ives, St Ives Chase, Turramurra, Wahroonga, Waitara, Warrawee, and West Pymble; as well as parts of Asquith, Chatswood, Chatswood West, Hornsby, Mount Colah, and Normanhurst. The electorate has undergone minor boundary changes, with the redistribution in 2016 shifting slightly south, gaining Castle Cove and parts of Chatswood from North Sydney while losing parts of Thornleigh, Normanhurst and Hornsby. The 2025 redistribution saw the electorate once again move south, gaining most of the City of Willoughby, while losing Asquith, Normanhurst, Hornsby, Waitara, as well as Hornsby Shire parts Wahroonga to Berowra. Small Ku-ring-gai Council parts of Wahroonga (Only North of the Coups Creek) were also moved to Berowra
