Beckenham (/ˈbɛkənəm/) was a constituency[n 1] in Greater London represented in the House of Commons of the UK Parliament from 2010 until its abolition for the 2024 general election by Bob Stewart, a member of the Conservative Party.

The constituency is mostly leafy and suburban — one widely known gazetteer summarised this in 2012: "The properties on these streets typically include a range of styles, from modern to Mock Tudor.

At the lower end of the market, a one bedroom period conversion flat on Turpington Lane near Bromley Common, or a one bedroom flat in a modern block on Homesdale Road, near the Bickley border, would demand an asking price of approximately £160,000.

This removed the three most Labour inclined wards of the borough, centered on Penge, and one other, taken from the more suburban parts that lean strongly or weakly Conservative.

The closest the Conservatives have ever come to losing this seat was at a by-election in November 1997, at the height of Tony Blair's 'honeymoon period' as Prime Minister, following the resignation of the previous MP Piers Merchant in a sex scandal.

Between 1957 and 1992 the long-serving MP for Beckenham was Sir Philip Goodhart, who was soon after 1979 discovered by Margaret Thatcher to be a right-of-centre or 'wet conservative' and consequently his career as a junior minister came to a quick end.

Before Sir Philip Goodhart, the former Conservative Chief Whip Patrick Buchan-Hepburn represented Beckenham in Parliament.

Following their review of parliamentary representation in South London, the Boundary Commission for England made revisions to this seat.
