The B4332 is a rural B-road in southwest Wales.
It starts in the centre of Eglwyswrw in northern Pembrokeshire, where it turns southeastward off the A487. The road then turns to head east through Llanfair Nant-gwyn before intersecting the A478 at a staggered crossroads. Shortly afterwards a spur of the B4332, leading from a point on the A478 immediately north of Blaenffos, comes in from the right.
The B4332 continues east then northeast through Boncath and Newchapel before descending steeply to cross the Cych River and enter Carmarthenshire. The climb back up on the other side is less steep.
Penlan Holiday Village is passed before the road enters Cenarth and ends at a T-junction on the A484 in the centre of the village.
Originally the B4332 went from Blaenffos to Cenarth, with today's spur being the original main line. The road from Eglwyswrw to Boncath was unclassified in 1922, but had become an extension of the B4329 by 1932. At some point between then and 1939 the B4332 took over this extension, giving the road its current route, complete with spur.
