Hampstead and Kilburn was a constituency created in 2010 and represented in the House of Commons from 2015 until its abolition for the 2024 general election by Tulip Siddiq of the Labour Party.

[3] The constituency was created for the 2010 general election in which it was won by Labour's Glenda Jackson with a majority of 42 votes being the most marginal result in England; one smaller majority nationally was achieved, in Fermanagh and South Tyrone, Northern Ireland.

Hampstead and Kilburn was in 2010 the closest three-way marginal seat as the third-placed candidate obtained 841 fewer votes than the winner, approximately 1% of the electorate.

In January 2013, Jackson announced that she would not seek re-election, one of 37 of her party's MPs who did so in the 2015 general election.

A small part of Queens Park ward was transferred from the former constituency of Brent South.
