Lwyncelyn is a village in Ceredigion, Wales, situated on the A487 trunk road approximately 2.7 mi (4.3 km) southwest of the town of Aberaeron and 2 mi (3.2 km) northeast of the village of Llanarth.

The Ceredigion coastline is 1.3 mi (2.1 km) miles away at the small shingle beach at Gilfach yr Halen.

The village has a petrol station with a convenience store and post office situated on the northern side of the A487, an animal feed store, a small home furnishing store, a farm shop and restaurant as well as a small chapel with cemetery, a village hall and a small caravan and camping park as well as a second camping site.

[3] The memorial hall/village hall (Llwyncelyn Neuadd y Pentref) is situated off the A487 and contains plaques in honour of local men who died in the two world wars.

[6] The local primary school (Penlôn) opened in 1878 and was closed in 2011[7] following a decline in student numbers from a high of 59 in 2006 to the review threshold of 20 in 2010 resulting in running costs per pupil being approximately 50% higher than the average for Ceredigion.
