The House of Braose (alias Breuse, Brewes, Brehuse, Briouze, Brewose etc., Latinised to de Braiosa) was a prominent family of Anglo-Norman nobles originating in Briouze, near Argentan, Orne, Normandy. Members of this family played a significant part in the Norman conquest of England and subsequent power struggles in England, Wales and Ireland in the 11th to 14th centuries.
The first English land-holding by the family was the feudal barony of Bramber in Sussex, granted by King William the Conqueror to William I de Braose (died 1093/1096) between the Norman Conquest of 1066 and the Domesday Book of 1086 in which he is shown as the holder of Bramber. Philip I made personal conquests in the Welsh Marches of Radnor and Builth. A moiety of the feudal barony of Barnstaple was inherited by William II from his mother. William III acquired the feudal barony of Kington c.1194 and the lordship of Gower in 1203, and a moiety of the feudal barony of Totnes in 1206. King John temporarily seized most of the lands of William III in 1208 but his infant son King Henry III (1216–1272) regranted most, except Barnstaple which was lost permanently, to his 3rd son Reginald. Reginald's son William V died leaving 4 daughters co-heiresses to all the family's Welsh lands, but Bramber and Gower passed back to the senior family line which held them until 1326 when William VII died leaving two daughters co-heiresses.

Matthew Paris (c.1200-1259) in his Historia Anglorum (folio 116) attributed the arms, Party per pale indented gules and azure, to William V de Braose (d.1230). They appear as a marginal drawing of an inverted shield referring to his "impious murder" (Nota impiam murthram).
