Bermondsey West was a parliamentary constituency centred on the Bermondsey district of South London. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom.

The constituency was created for the 1918 general election and abolished for the 1950 general election.

The constituency, when it was created in 1918, comprised the wards numbered One, Two, Three and Four of the Metropolitan Borough of Bermondsey, in the County of London. This was the south-western part of the borough, and was similar in extent to the preceding Bermondsey Division of the parliamentary borough of Southwark.

It covered South Bermondsey ward and most of London Bridge & West Bermondsey ward, together with small sections of North Bermondsey, Chaucer and Old Kent Road wards, in the modern day London Borough of Southwark.
