Villiers is an aristocratic family in the United Kingdom. Over time, various members of the Villiers family were made knights, baronets, and peers. Peerages held by the Villiers family include the dukedoms of Buckingham (1623–1687) and Cleveland (1670–1709), as well as the earldoms of Anglesey (1623–1661), Jersey, and Clarendon. Perhaps the most prominent members of the family were those who received the two dukedoms: George Villiers, 1st Duke of Buckingham (1592–1628) rose to fame and influence as favourite of King James I of England, while Barbara Villiers, Duchess of Cleveland (1640–1709) became a mistress of King Charles II of England, by whom she had five children.

Duke of Buckingham, referring to Buckingham, is an extinct title that has been created several times in the peerages of England, Great Britain, and the United Kingdom. There were creations of double dukedoms of Buckingham and Normanby and of Buckingham and Chandos. The last holder of the dukedom died in 1889.
