Walter II de Clifford (c. 1160 – 17 January 1221) was a Welsh Marcher Lord and High Sheriff in England.
He was born in Clifford Castle, near Hay-on-Wye, Herefordshire the son of Walter I de Clifford (1113–1190).
Walter served as High Sheriff of Herefordshire in 1199,1207–1208 and 1216. He was a close associate of William de Braose and although he held back from William's rebellion in March 1208, was not thought to have done enough to check it. As a result King John dismissed him from his Marcher barony of Clifford and made his son Walter III de Clifford de facto lord instead.
Walter had married Agnes Cundy of Kent in 1185 and was succeeded by his sons, Walter III de Clifford (c1190–c1263) and Roger Clifford, who founded the line of Northumbrian Cliffords. He had at least three other sons, Giles, Richard and Simon, as well as daughters Maud, Basilia and Cecilia.
