Hayes and Harlington is a constituency[n 1][n 2] in the west of London represented in the House of Commons of the UK Parliament since 1997 by John McDonnell of the Labour Party, who also served as the Shadow Chancellor of the Exchequer from 2015 to 2020 until his suspension and whip withdrawn on 23 July 2024, as a result of voting to scrap the two child benefit cap. He now sits as an Independent MP until the whip is re-established.

The seat, created in 1950, is 1 of 49 won (held or gained) by a Labour candidate in 2017 from a total of 73 covering London. In the period 1983-1997 the seat was Conservative-represented. From 1981 until 1983 the seat was represented, by defection, by a member of the Social Democratic Party (SDP) which later merged into the Liberal Democrats. From 1950 until 1983 the seat was won by Labour candidates.

Its London Heathrow Airport component has most of the border with Buckinghamshire and Surrey and its shape is near-square with a north-east square attached: Hayes and Yeading. Harlington is among the lowest-population components of the seat; with Hayes it gives its name to a railway station and with Hayes was the name of an urban district.
