King's Cross Central (KXC) is a multi-billion pound mixed-use property development in central London.^{[citation needed]} The site is owned and controlled by London and Continental Railways (LCR) and Exel, which selected Argent St George to be the developer for King's Cross Central, after an extensive selection process. The site consists of approximately 65 acres (25 hectares) of former railway lands, mostly to the north of King's Cross and St Pancras mainline railway stations. The site is largely determined by three boundaries: the existing East Coast Main Line railway leading out of King's Cross; York Way, a road marking the division between Camden and Islington; and the new railway line, High Speed 1 (HS1), formerly known as the Channel Tunnel Rail Link, which curves around the site to the north and west.

A small section of the project, known as the "Triangle Site", falls within the boundaries of Islington. Camden Council granted outline planning permission for the main part of the site in early 2006. This has now been approved by the national government and the Mayor of London, although separate planning permission for the Triangle Site is still required from Islington Council.
