The London and North Western Railway Precedent Class was a class of seventy 2-4-0 steam locomotives originally designed for express passenger work.

They were designed by F. W. Webb and built by the LNWR's Crewe Works between 1874 and 1882.

All seventy carried names from new, many of which had been used on withdrawn locomotives.

The remaining eight were rebuilt as Improved Precedents in the 1890s; they retained their 7⁄8 inch (22.2 mm) thick frames – the renewals had 1-inch (25.4 mm) frames.

Two of the unrenewed locomotives were scrapped in 1907, and two in the 1910s, with four passing to the London Midland and Scottish Railway in 1923.
