Croydon West is a borough constituency which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom from 1950 to 1955 by the first past the post system of election.

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat was re-established for the 2024 general election.

[2] 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.

For the entirety of its first iteration in the 1950s, Croydon West's Member of Parliament was Conservative Richard Thompson.

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.
