The British Rail Class 555 Metro is a class of electric multiple units, commissioned and built for the Tyne and Wear Passenger Transport Executive (Nexus) by the Swiss company Stadler Rail, at a total cost of £362 million, for use on the Tyne and Wear Metro. For operation on Network Rail controlled tracks between Pelaw Junction and Sunderland, they are designated on TOPS as the Class 555.

To facilitate operation of the new trains, a new Metro Fleet Depot in Gosforth has been built, and 40 of the 60 stations are having platform heights modified. Nexus has consulted with both drivers and passengers on the fine details of cab and carriage interior design.

On 18 December 2024, the first unit entered passenger service. Eventually the 46 new units will replace the Tyne and Wear Metrocars, which have been in use since the system opened in 1980.
