Thomas Berkeley, 5th Baron Berkeley Thomas Berkeley, 5th Baron Berkeley Thomas Berkeley, "de jure" 5th Baron Berkeley, (b. 1472 - 22 January 1532) was a British soldier and aristocrat. He was born to Sir Maurice Berkeley, "de jure" 3rd Baron Berkeley, and Isabel Meade, in England. He was the younger brother to Maurice Berkeley, "de jure" 4th Baron Berkeley, and had a younger brother, James, and younger sister, Anne.

Baron Berkeley that the barony by writ was deemed, extraordinarily, to be in effect a feudal barony (or barony by tenure), dependent on the tenure of Berkeley Castle. Thus when William Berkeley, 1st Marquess of Berkeley, 2nd Baron Berkeley (1426–1492), "William the Waste-All", alienated Berkeley Castle to the king, he effectively disinherited his younger brother from the barony by writ. The heir apparent is his son the Hon. Thomas FitzHardinge Gueterbock (b. 1969) The Earldom of Berkeley, together with the Viscountcy Dursley, was separated from the barony in 1882, but the accession was not fully established. In 1942 both titles became extinct
