The first London and North Eastern Railway (LNER) Class A2 was a class of 4-6-2 steam locomotive designed by Vincent Raven. Two were built by the North Eastern Railway (as NER class 4.6.2[1]) in 1922 before the grouping and another 3 by the LNER in 1924. Their LNER numbers were 2400–2404. All five locomotives were named by the LNER.

Because of the great length of their parallel boilers, the Raven pacifics earned the nickname 'Skittle-alleys'.

The Great Northern Railway's Class A1, which was a more technically advanced machine, was chosen as the LNER's standard express passenger locomotive so no more Raven A2s were built.

All the Raven A2s were withdrawn in 1936–1937 and none have survived into preservation.
