Duhonw is a rural community in Powys, Wales, to the south of Builth Wells (Welsh: Llanfair ym Muallt), comprising scattered farms and dwellings. Covering an area of 4,376 hectares (16.90 sq mi), it is bounded to its north by the Afon Irfon, to its south by Mynydd Epynt and Banc y Celyn and to its east the rivers Duhonw and Wye (Afon Gwy). Llangammarch Wells' (Welsh: Llangamarch) is to its west.
The 2011 census showed 14.6% of the population could speak Welsh, a rise from 9.2% in 2001.
Duhonw Community Council was created following a 1985 review by the Local Government Boundary Commission for Wales, amalgamating the four small communities of Llanddewi'r Cwm, Llangynog, Llanynis and Maesmynis.
