William de Braose, Third Lord of Bramber (d. ca. 1180) was the eldest son of Philip de Braose[?], Second Lord of Bramber. William married Bertha de Pitres[?], daughter of Miles of Gloucester[?], Earl of Hereford.

In 1174, William became sheriff of Hereford. He was succeeded as Lord of Bramber by his son, William.
