LNER Class P2 No. 2007 Prince of Wales is a 2-8-2 "Mikado" steam locomotive being built at Darlington Locomotive Works, England, and managed by the A1 Steam Locomotive Trust. It will be the seventh member of its class and the only P2 in existence; the original six were built between 1934 and 1936 for the London and North Eastern Railway (LNER) to a design by Nigel Gresley, and employed to haul heavy passenger trains on the Edinburgh to Aberdeen line. The P2s were declared Britain's most powerful express passenger engines, although none were preserved.

The A1 Trust announced the project in 2013, following the completion and success of its first new build locomotive, LNER Peppercorn Class A1 No. 60163 Tornado, in 2008. Construction on Prince of Wales began in 2014 with its design based on P2 No. 2001 Cock o' the North with some modifications to improve maintenance, address historic problems, and comply with modern railway operations. It is expected to be complete in 2025 at an estimated cost of £6 million, after which it will run on the mainline and heritage railways.
