National Car Parks (NCP) is the United Kingdom’s largest private car park operator, with over 200,000 spaces across more than 700 locations in towns and cities, railway stations and at airports.

NCP also had a growing service business, but this demerged from NCP in 2007. It is called NSL Services Group, and was previously called NCP Services Group. They also operated a bus company in London, called NSL Buses, and this was previously known as NCP-Challenger.

NCP was founded in 1931 by Colonel Frederick Lucas.
