King's Cross Thameslink station is a closed railway station in central London, England. It is located on Pentonville Road, around 250 metres east of King's Cross mainline station. At the time of closure, in 2007, it was served by Thameslink trains and managed by First Capital Connect.
The station opened in 1863 as King's Cross Metropolitan. It was one of the initial seven stations on the Metropolitan Railway, London's first underground line, which ran between Paddington and Farringdon. The Metropolitan had been planning for the station since 1851, when King's Cross mainline station was constructed, to provide a connection between the Great Western Railway at Paddington and the Great Northern Railway out of King's Cross.
