Maurice de Berkeley, 2nd Baron Berkeley (1281 – 31 May 1326), The Magnanimous, feudal baron of Berkeley, of Berkeley Castle in Gloucestershire, England, was a peer. He rebelled against King Edward II and the Despencers. His epithet, and that of each previous and subsequent head of his family, was coined by John Smyth of Nibley (died 1641), steward of the Berkeley estates, the biographer of the family and author of Lives of the Berkeleys.
