Docklands Light Railway rolling stock is the passenger trains and service vehicles (collectively known as 'rolling stock') used on the Docklands Light Railway (DLR), which serves the London Docklands area in the east of London.

The passenger stock consists of high-floor, bi-directional, single-articulated EMUs. The trains are formed from sets of two or three semi-permanently connected cars, the increase to three-car trains introduced on the busiest routes from 2010, following substantial platform extension works. The automation system is a GoA3 driverless system, which requires a Passenger Service Agent (PSA) to operate the doors and, when necessary, manually drive the train.

There have been three different main types of DLR rolling stock, but only two of them (the B90/B92/B2K fleet and the B07 fleet) are in operation; the original P86/P89 stock having been withdrawn and sold to Essen, Germany.

From 2024, a new fleet of 54 trains built by CAF will replace older rolling stock and provide additional capacity.
