Baron Clifford is a title in the Peerage of England created by writ of summons on 17 February 1628 for Henry Clifford, the heir of Francis Clifford, 4th Earl of Cumberland. Francis was believed to hold the Barony de Clifford, created in 1299, which could therefore be used to give Henry a seat in the House of Lords during his father's lifetime via a writ of acceleration. However, it would later be determined that the barony had in fact passed to his niece, Lady Anne Clifford. The summons of 1628 therefore unintentionally created a new barony, held by Henry. In 1641, on his father's death, Henry inherited the earldom of Cumberland, which became extinct upon his own death in 1643.
