Earl's Court tube station is a Grade II listed London Underground station in Earl's Court, London, on the District and Piccadilly lines. It is an important interchange for both lines and is situated in both Travelcard Zone 1 and Zone 2. The station has an eastern entrance on Earl's Court Road and a western entrance on Warwick Road. Another former entrance allowed passengers to enter the station from the other side of Warwick Road, via a ticket hall and subway leading to a concourse beneath the District line platforms. Earl's Court is a step-free tube station; the Earls Court Road entrance provides lift access between street and platform levels.

The District line is a London Underground line running from Upminster in the east and Edgware Road in the west to Earl's Court in west London, where it splits into multiple branches. One branch runs to Wimbledon in south-west London and a short branch, with a limited service, only runs for one stop to Kensington (Olympia). The main route continues west from Earl's Court to Turnham Green after which it divides again into two western branches, to Richmond and Ealing Broadway.
