The West Wales lines (Welsh: Llinellau Gorllewin Cymru) are a group of railway lines from Swansea through Carmarthenshire to Pembrokeshire, West Wales. The main part runs from Swansea to Carmarthen and Whitland, where it becomes three branches to Fishguard, Milford Haven and Pembroke Dock. Before the rail cuts of the 1960s, there were routes to Cardigan, Newcastle Emlyn, Llandysul, and via Lampeter, cross-country from Carmarthen to Aberystwyth.
