Marquess Camden is a title in thePeerage of the United Kingdom. It was created in 1812 for the politicianJohn Pratt, 2nd Earl Camden.^[1] The Pratt family descends fromSir John Pratt,Lord Chief Justice from 1718 to 1725. His third son from his second marriage,Sir Charles Pratt, was also a prominent lawyer and politician and served asLord Chancellor between 1766 and 1770. In 1765 he was raised to thePeerage of Great Britain asBaron Camden, ofCamden Place in theCounty of Kent,^[2] and in 1786 he was further honoured when he was createdViscount Bayham, ofBayham Abbey in the County of Kent, andEarl Camden.^[3] These titles are also in the Peerage of Great Britain.^[4] Lord Camden was married to Elizabeth, daughter of Nicholas Jeffreys, of The Priory,Brecknockshire, in Wales.

Their son, the second Earl, was a politician and notably served asLord Lieutenant of Ireland and asLord President of the Council. In 1812 he was createdEarl of the County of Brecknock (usually shortened to Earl of Brecknock) andMarquess Camden.^[5] His son, the second Marquess, representedLudgershall,Bath andDunwich in theHouse of Commons and also served asLord Lieutenant of Brecknockshire. In 1835 Lord Camden was called to theHouse of Lords through awrit of acceleration in his father's junior title of Baron Camden. His son, the third Marquess, briefly sat as aMember of Parliament forBrecon in 1866, before he succeeded his father and took his seat in the House of Lords. On his early death, the titles passed to his three-month-old son, the fourth Marquess. He was notablyLord Lieutenant of Kent from 1905 to 1943. As of 2017^[update] the peerages are held by his grandson, the sixth Marquess, who succeeded his father in 1983.

Lord Michael Pratt was a younger son of the fifth Marquess.

The family seat is Wherwell House, nearAndover, Hampshire. Until the early 1980s, the family also owned the Bayham Abbey Estate, nearLamberhurst, Kent.
