Killara (/kɪlɑːrə/) is a suburb on the Upper North Shore of Sydney in the state of New South Wales, Australia.

Killara is located 14 kilometres (8.7 mi) north-west of the Sydney central business district in the local government area of Ku-ring-gai Council.

The first Europeans to inhabit the area were convicts and their overseers, who set up a timber-getting camp around 1805, on the banks of the Lane Cove River.

On 5 April 1821, five crown grants of land comprising Killara were given to settlers by Lachlan Macquarie, including 40 acres to Joseph Fidden.

[3] Killara later became the home of the architect Harry Seidler, whose home—designed by him and his wife Penelope in the 1960s—can still be seen in Kalang Avenue.

[4] Marian Street Theatre played a significant role in the cultural life of the North Shore.

[12][13] A short-lived private school in Killara, Abbotsholme College, counted two future prime ministers[which?]

Residents usually travel to nearby suburbs of Gordon, Macquarie Park and Chatswood for regular shopping.

For federal elections, Killara lies in the electorate of Bradfield, currently represented by Paul Fletcher.
