Canary Wharf is an Elizabeth line station in Canary Wharf in East London, England. The station forms an artificial island in the West India Docks. The five upper levels of the station are a mixed-use development known as Crossrail Place. It is on the Abbey Wood branch of the Elizabeth line between Whitechapel and Custom House. Construction began in May 2009, and the station opened on 24 May 2022 when the section between Paddington and Abbey Wood stations began services. During the project's development the station was named Isle of Dogs, before the current name was adopted. The station was developed under a fixed price contract of £500 million with £350 million provided from the Crossrail budget and £150 million from the Canary Wharf Group with Crossrail spending an additional £80 million on safety improvements before it was opened.

The Elizabeth line is a high-frequency hybrid urban–suburban rail service in London and its suburbs. It runs services on dedicated infrastructure in central London from the Great Western Main Line west of Paddington station to Abbey Wood and via Whitechapel to the Great Eastern Main Line near Stratford; along the Great Western Main Line to Reading and Heathrow Airport in the west; and along the Great Eastern Main Line to Shenfield in the east. The service is named after Queen Elizabeth II, who officially opened the line on 17 May 2022 during her Platinum Jubilee year; passenger services started on 24 May 2022. Despite being named under the same system as London Underground lines, and having sections which are underground, the Elizabeth line is not classified as a London Underground line.
