The Peerage of the United Kingdom comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Act of Union in 1801, when it replaced the Peerage of Great Britain. New peers continued to be created in the Peerage of Ireland until the formation of the Irish Free State in 1922.

The ranks of the peerage are Duke, Marquess, Earl, Viscount, and Baron.^[1]

Until the House of Lords Act 1999 was passed, all Peers of the United Kingdom were members of the House of Lords. However, from that date most of the hereditary peers were expelled as part of Parliamentary reform.
