Maesyronnen Chapel is about 1 mile (2 km) north of the village of Glasbury, Powys, Wales (grid reference SO176410). It is designated by Cadw as a Grade I listed building. The chapel is one of the earliest Nonconformist chapels to be built in Wales, and is the only chapel existing from that time to be largely unchanged and still in use as a chapel. It is currently administered by the United Reformed Church. The attached ccaretaker's cottage is also listed at Grade I.
