The Peerage of Ireland consists of those titles of nobility created by the English monarchs in their capacity as Lord or King of Ireland, or later by monarchs of the United Kingdom of Great Britain and Ireland. It is one of the five divisions of Peerages in the United Kingdom. The creation of such titles came to an end in the 19th century. The ranks of the Irish peerage are duke, marquess, earl, viscount and baron. As of 2016, there were 135 titles in the Peerage of Ireland extant: two dukedoms, ten marquessates, 43 earldoms, 28 viscountcies, and 52 baronies. However, these titles have no official recognition in the Republic of Ireland, with Article 40.2 of the Constitution of Ireland forbidding the state conferring titles of nobility and stating that an Irish citizen may not accept titles of nobility or honour except with the prior approval of the Irish government.
The Peerage Act 1963 is an Act of the Parliament of the United Kingdom that permits female hereditary peers and all Scottish hereditary peers to sit in the House of Lords and allows newly inherited hereditary peerages to be disclaimed.
The Peerage of England comprises all peerages created in the Kingdom of England before the Act of Union in 1707. From that year, the Peerages of England and Scotland were closed to new creations, and new peers were created in a single Peerage of Great Britain. There are five peerages in the United Kingdom in total.
The Peerage of the United Kingdom is one of the five Peerages in the United Kingdom. It comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Acts of Union in 1801, when it replaced the Peerage of Great Britain.

In the United Kingdom, life peers are appointed members of the peerage whose titles cannot be inherited, in contrast to hereditary peers. Life peers are appointed by the monarch on the advice of the prime minister. With the exception of the Dukedom of Edinburgh awarded for life to Prince Edward in 2023, all life peerages conferred since 2009 have been created under the Life Peerages Act 1958 with the rank of baron and entitle their holders to sit and vote in the House of Lords, presuming they meet qualifications such as age and citizenship. The legitimate children of a life peer appointed under the Life Peerages Act 1958 are entitled to style themselves with the prefix "The Honourable", although they cannot inherit the peerage itself. Prior to 2009, life peers of baronial rank could also be so created under the Appellate Jurisdiction Act 1876 for senior judges.
