The London and North Western Railway (LNWR) George the Fifth Class was a class of 4-4-0 passenger steam locomotive.

The locomotives were introduced in 1910 by Charles Bowen-Cooke following the coronation of George V, and construction continued until 1915. They were essentially superheated versions of the LNWR Whale Precursor Class. At the same time, similar non-superheated Queen Mary Class engines were also built but all of these acquired superheaters as the advantages of superheating became clear and were absorbed into the George the Fifth Class.

A total of 90 Georges were built, and all were named. The LNWR reused names and numbers from withdrawn locomotives, with the result that the numbering system was completely haphazard.

All of the Georges passed into London Midland and Scottish Railway (LMS) ownership on the grouping in 1923. The LMS gave them the power classification 3P. The LMS renumbered them into a more logical series of 5320–5409, and later in 1936/37 those had not been then withdrawn were again renumbered by the addition of 20000 into the 25320–25409 series to make room for Black Fives. Also at this time a few of the names were removed so that they could be applied to new LMS Jubilee Class engines.

Withdrawals started in 1935, and by 1939 only nine remained. British Railways (BR) inherited three in 1948: 25321, which was withdrawn in February that year, and 25350 and 25373, which were allocated the BR numbers 58011/2 in March but never carried them as both were withdrawn in May that year.

None has been preserved.

The George the Fifth Steam Trust is building a George the Fifth class locomotive named after Prince George.
