King's Cross railway station, also known as London King's Cross, is a major London railway terminus opened in 1852. It stands on the northern edge of central London, at the junction of the Euston Road and York Way, in the London Borough of Camden on the border of the London Borough of Islington. It is one of 18 UK stations managed by Network Rail.

King's Cross is the southern terminus of the East Coast Main Line, one of Britain's major railway backbones. Some of its most important long-distance destinations are Leeds, Newcastle and Edinburgh. It also hosts outer-suburban services to Bedfordshire, Hertfordshire and Cambridgeshire, and fast regional services to Peterborough, Cambridge and Kings Lynn.

Immediately to the west across Pancras Road is St Pancras International, the London terminus of the Midland Main Line, international Eurostar trains and high-speed trains to Kent via High Speed 1, and a major interchange for Thameslink services between Bedford and Brighton. The two stations are operationally completely separate, but as they are adjacent they may be regarded as a single complex for interchange purposes. They share King's Cross St. Pancras tube station on the London Underground network, where six Underground lines meet. Taken together, these two main-line stations and the associated underground station form one of Britain's biggest transport hubs. The station is also within walking distance of Euston Station, the southern terminus for the West Coast Main Line.
