The Midland Railway 690 Class was a class of six 0-4-4T built by Beyer, Peacock and Company in 1869 for use in the London area.

They were double-framed Kirtley engines with a back tank, i.e. the tank was placed beneath the bunker.

The 780 Class was similar.

In 1898 they were transferred to the duplicate list as 690A–695A.

All were inherited by the London, Midland and Scottish Railway in 1923.
