Llangynidr is a village, community and electoral ward in Powys, Wales, about 4 miles (6.4 km) west of Crickhowell and 9 miles (14.5 km) south-east of Brecon. The River Usk flows through the village as does the Monmouthshire and Brecon Canal. It is in the historic county of Brecknockshire.
The village is located four miles west of Crickhowell and nine miles southeast of Brecon, beside the River Usk and the Monmouthshire and Brecon Canal. It is situated on the B4558 just to the south of where this road diverges from the A40 trunk road. The stone bridge across the river dates from approximately 1700 and is a Grade I listed building. The canal has five locks and an aqueduct in the vicinity of the village.
The village is notionally divided into Upper and Lower Llangynidr. The remains of what may be a medieval reeve's house have been discovered in the course of archaeological excavations in the centre of the village. The village has two public houses, a village shop and a primary school.
Sir William Herbert, Knight of Raglan Castle, was granted the manors of Tretower Castle and Crickhowell just after the accession of Edward IV in 1442. At that time this village was part of the manor of Tretower.
On the moors to the southeast of the village lies the Chartist Cave, the name of which derives from 1839 when Chartist rebels used the cave to stockpile weapons in advance of their march on Newport. There is a plaque at the entrance of the cave commemorating their actions.
