Humphrey de Bohun was the name of a number of men in medieval England, all members of a prominent noble family.

The 7th Earl of Hereford was the last of the Bohun line. His great estate was split between his two daughters: Mary de Bohun, who married the future Henry IV (who was created Duke of Hereford before he was king), and Eleanor, who married Thomas of Woodstock.

The name Humphrey recurs among the two sisters' children and grandchildren, including Mary's son Humphrey, Duke of Gloucester, Eleanor's son Humphrey Earl of Buckingham (d. 1399), and her grandson Humphrey Stafford, 1st Duke of Buckingham.
