Croydon West was a borough constituency represented in the House of Commons of the Parliament of the United Kingdom from 1950 to 1955. It elected one Member of Parliament (MP) by the first past the post system of election.

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat will be re-established for the next general election. It will comprise primarily of the majority of the existing (to be abolished) constituency of Croydon North, with the addition of Croydon town centre and the community of Waddon.^[1]

Croydon West was a short-lived seat for the 1950 general election, creating three seats in the County Borough of Croydon from the previous two, also taking in areas from the East Surrey constituency to the south.

Croydon West took in areas of the former Croydon North and Croydon South constituencies, and East Surrey. It bordered Croydon East, Croydon North, East Surrey and Mitcham.

All three Croydon constituencies were abolished five years later at the 1955 general election, re-creating Croydon South and creating Croydon North East and Croydon North West seats.

For all of its history, Croydon West's Member of Parliament was Conservative Richard Thompson. It was contested in two elections: the 1950 general election and the 1951 general election. Prior to 1950, Croydon South had been held by Labour and most of the Labour voters were re-drawn into Croydon West, making it a marginal seat.
