William de Braose, 3rd Lord of Bramber (fl. 1135–1179) was a 12th-century Marcher lord who secured a foundation for the dominant position later held by the Braose family in the Welsh Marches. In addition to the family's English holdings in Sussex and Devon, William had inherited Radnor and Builth, in Wales, from his father Philip. By his marriage he increased the Braose Welsh holdings to include Brecon and Abergavenny.

William remained loyal to King Stephen during the 12th-century period of civil war. He became a trusted royal servant during the subsequent reign of Henry II, accompanying the king on campaigns in France and Ireland. He served as sheriff of Herefordshire from 1173 until 1175. The family's power reached its peak under his son William during the reigns of kings Richard I and John.
