St Brides Netherwent (Welsh: Sant-y-brid) is a parish and largely deserted village in Monmouthshire, south-east Wales.
The church of Saint Bridget or Brigid is set in quiet countryside, adjoining the site of a deserted medieval village.
It is so named to distinguish it from the village of St Brides Wentloog, to the west of Newport.
"Netherwent" is the English name given from the Norman period onwards to the Welsh cantref of Gwent-is-coed (Gwent beneath the wood, i.e. Wentwood), with "-went" deriving from the Roman town of Venta which became Caerwent.
Aside from today's farmhouses outlying the clustered centre, St Brides Netherwent was abandoned in the 18th century.
