Dalkeith is an affluent suburb of Perth, Western Australia within the City of Nedlands.

[2] The suburb takes its name from a cottage built in 1833 by Captain Adam Armstrong and his sons, early settlers of the area who arrived aboard Gilmore.

As at 2021, Dalkeith was the most expensive suburb for houses in Western Australia, with a median price of $2.9 million.

In 2005 the University of Western Australia entered into an agreement with the state government to redevelop the site, including a museum, aged care and residential apartments.

[8] In September 2007 UWA withdrew from the agreement, citing delays and restrictions caused by the heritage status of the site.
