Bury South is a borough constituency represented in the House of Commons of the Parliament of the United Kingdom since 2019 by Christian Wakeford.

The constituency was created in 1983 from parts of the former seats of Middleton and Prestwich & Bury and Radcliffe, both of which were Labour-Conservative marginals, held by Labour on slim majorities at the 1979 election.

Lewis belonged to the Labour Party and was a minister during the Blair and Brown governments, but was suspended in 2018 due to allegations of indecent behaviour.

The seat covers Prestwich, Whitefield and Radcliffe, towns that were absorbed into the Metropolitan Borough of Bury in 1974, plus, since 2024, the ward of Kersal and Broughton Park from the City of Salford.

Radcliffe is a former mill town which declined after the loss of industry, with its only secondary school shut down; it is attempting regeneration as a commuter suburb and features a large park-and-ride Metrolink station.
