Thomas de Berkeley (c. 1293 or 1296 – 27 October 1361), The Rich, feudal baron of Berkeley, of Berkeley Castle in Gloucestershire, England, was a peer. His epithet, and that of each previous and subsequent head of his family, was coined by John Smyth of Nibley (d.1641), steward of the Berkeley estates, the biographer of the family and author of "Lives of the Berkeleys".


He was the eldest son and heir of Maurice de Berkeley, 2nd Baron Berkeley by his wife Eve la Zouche.


In 1327 he was made joint custodian of the deposed King Edward II, whom he received at Berkeley Castle. He was later commanded to deliver custody of the king to his fellow custodians, namely John Maltravers, 1st Baron Maltravers and Sir Thomas Gournay. He left the king at Berkeley Castle and with heavy cheere perceiving what violence was intended he journeyed to Bradley. The king was murdered at Berkeley Castle during his absence. As an accessory to the murder of the deposed king, he was tried by a jury of 12 knights in 1330 and was honourably acquitted.
