Kemeys Commander lies some 3 miles north west of Usk on the banks of the River Usk, in Monmouthshire, Wales. Kemeys Commander sits south of Llanvihangel Gobion, south east of Llanover, north west of Usk and north east of Pontypool.

The village comprises a few farms, cottages, and a church, and its unusual name is derived from the fact that the patronage of the church was at one time held by the Knights Templars and was a commandery, as their houses were termed.

The church of All Saints has some features dating back to the 13th Century.

The village lies within a bend of the River Usk, and the Usk Valley Walk passes by on the west bank of the river. The river rises on the Black Mountain above the Usk Reservoir from where it tumbles for most of its upper and middle reaches through the beautiful Brecon Beacons National Park. After the River Usk passes through the market town of Brecon and the pretty little town of Crickhowell, the river leaves the National Park at Abergavenny and meanders through the farmland of the broader valley beyond. Shortly after passing Kemeys Commander and Usk the river becomes tidal and enters the estuary at Newport, where it mixes with the waters of the River Severn in the Bristol Channel.
