The Division of Petrie is an Australian Electoral Division in Queensland.

The division was created in 1949 and named after Andrew Petrie (1798–1872), a noted civil engineer, pioneer, and explorer, and the first free settler in Brisbane (1837).

The electorate has a higher-than-average percentage of pensioners and self-funded retirees, and is mainly residential, with some light industrial and commercial activities.

Originally a safe Liberal seat, it has become much more marginal since the late 1970s. From 1975 to 2022, it was held by the party of government for all but one term.

Ahead of the 2016 federal election, ABC psephologist Antony Green listed the seat in his election guide as one of eleven which he classed as bellwether electorates.^[1]

In the 2022 federal election, Luke Howarth retained the seat with 54.4% of the vote, resulting in the seat becoming marginal after the election.^[2]

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]

Petrie is located in the northern suburbs of Brisbane, and since a redistribution ahead of the 2010 Federal Election has been centred on the Redcliffe Peninsula.

In the City of Moreton Bay, it includes Clontarf, Kippa-Ring, Margate, Redcliffe, Rothwell, Deception Bay, Scarborough, Woody Point, North Lakes, Mango Hill, Griffin and part of Burpengary.

In the City of Brisbane, it includes Bald Hills, Bracken Ridge, Carseldine and Fitzgibbon, and parts of Aspley and Bridgeman Downs.
