Valleys & Cardiff Local Routes (formerly Valley Lines) is the urban and suburban rail network radiating from Cardiff, Wales. It includes lines within the city itself, the Vale of Glamorgan and the South Wales Valleys.

The services are currently operated by Transport for Wales Rail. In total, it serves 81 stations in six unitary authority areas: 20 in the city of Cardiff, 11 in the Vale of Glamorgan, 25 in Rhondda Cynon Taf, 16 in Caerphilly, 8 in Bridgend and 5 in Merthyr Tydfil.

Services on these routes are currently provided by a transitional fleet of Class 150 DMUs, Class 231 Diesel–electric multiple units and Class 756 tri-mode multiple units. They are typically end-to-end, in that they run from one branch terminus, through Cardiff Queen Street station, to another branch terminus, e.g. from Pontypridd to Barry Island.

The major hubs of the network are Cardiff Queen Street and Cardiff Central. Other hubs are Pontypridd, Bridgend and Barry.
