This is a list of the present and extant Barons (Lords of Parliament, in Scottish terms) in the Peerages of England, Scotland, Great Britain, Ireland, and the United Kingdom. Note that it does not include those extant baronies which have become merged (either through marriage or elevation) with higher peerage dignities and are today only seen as subsidiary titles. For a more complete list, which adds these "hidden" baronies as well as extinct, dormant, abeyant, and forfeit ones, see List of Baronies.

This page includes all life barons, including the Law Lords created under the Appellate Jurisdiction Act 1876. However hereditary peers with the rank of viscount or higher holding also a life peerage are not included.
