Conwil was a railway station near the village of Cynwyl Elfed in Carmarthenshire, Wales, serving the hamlet and the rural locale.

It was once a thriving railway station, transporting both passenger traffic and locally produced goods, including wool, livestock, milk and timber.

In neighbouring Bronwydd, a 1 mile long section of the line was reopened in spring 1978 for tourists and named the Gwili Railway.

Plans were underway in 2012 to extend the line southwards to the site of Abergwili Junction.

[5] Seven derelict bridges crossing the Gwili lie between Conwyl itself and Llanpumpsaint; the cost of restoring them is a major factor delaying the reopening of the line up to Llanpumpsaint.
