Brentford and Isleworth (/ˈzəlwərθ/ EYE-zəl-wərth) is a constituency represented in the House of Commons of the UK Parliament. It forms the eastern part of the London Borough of Hounslow. Since 2015, it has been represented by Ruth Cadbury of the Labour Party.

Following the completion of the 2023 review of Westminster constituencies, the seat was subjected to boundary changes which moved Whitton from Twickenham into the constituency, and moved Chiswick to the newly created constituency of Hammersmith and Chiswick.
