Villiers (/ˈvɪlərz/ VIL-ərz) 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 (since 1697), and Clarendon (since 1776). 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.
