Hackney is an inner-eastern suburb of Adelaide, South Australia, in the City of Norwood Payneham St Peters.

The O-Bahn Busway passes along Hackney Road, part of the City Ring Route, which forms its western boundary.

[2][3][4] Romilly House in the southwest corner of the suburb, on North Terrace, is also listed on the Heritage Register.

Prior to the 2018 election, the state Labor government decided to build in 2016–2017 a $160 million tunnel for the O-Bahn Busway from north of North Terrace, Hackney, through the Adelaide Park Lands to the corner of Grenfell Street and East Terrace on the eastern edge of the Adelaide city centre.

The cost/benefit ratio of this project was questioned, traffic disruption was considerable, and the Labor party did not win the 2018 election.
