King's Cross St. Pancras is a London Underground station on Euston Road in the Borough of Camden, Central London. It serves King's Cross and St Pancras main line stations in fare zone 1, and is an interchange between six Underground lines. The station was one of the first to open on the network; as of 2021, it is the most used station on the network for passenger entrances and exits combined.
The station opened in 1863 as part of the Metropolitan Railway, subsequently catering for the Hammersmith & City and Circle lines. It was expanded in 1868 with the opening of the City Widened Lines, and the Northern and Piccadilly platforms opened in the early 20th century. During the 1930s and 1940s, the station was restructured and partially rebuilt to cater for expanded traffic.
