Caledonian Road is a station on the Piccadilly line of the London Underground, between King's Cross St. Pancras and Holloway Road, and in Travelcard Zone 2. It was opened on 15 December 1906 by the Great Northern, Piccadilly and Brompton Railway. The building was designed by Leslie Green.

The Piccadilly line is a deep-level London Underground line running from the north to the west of London. It has two branches, which split at Acton Town, and serves 53 stations. The line serves Heathrow Airport, and some of its stations are near tourist attractions such as Piccadilly Circus and Buckingham Palace. The District and Metropolitan lines share some sections of track with the Piccadilly line. Printed in dark blue on the Tube map, it is the sixth-busiest line on the Underground network, with nearly 218 million passenger journeys in 2019.
