Die Peerage of the United Kingdom umfasst alle Peer-Würden, die im Vereinigten Königreich von Großbritannien und Irland nach dem Act of Union 1800 geschaffen wurden. Die Peerage of the United Kingdom ersetzte somit die Peerage of Great Britain. In der Peerage of Ireland wurden dennoch neue Titel geschaffen, was erst mit der Unabhängigkeit Irlands 1922 endete.
Bis zur Verabschiedung des House of Lords Act 1999 hatten alle Peers einen Sitz im House of Lords. Die Ränge der britischen Peerage sind (mit den ungefähren deutschen Entsprechungen): Duke (Herzog) Marquess (Markgraf) Earl (Graf) Viscount („Vizegraf“) und Baron (Freiherr), erblich oder „auf Lebenszeit“ (engl. „for life“)
In der folgenden Tabelle werden nur aktuell geführte Titel britischer Peers, sowie Titel auf Lebenszeit im Vereinigten Königreich gelistet. Höhere oder gleichwertige Titel in anderen Peerages werden genannt. Es ist jedoch zu beachten, dass Mitglieder der engeren königlichen Familie, die einen Adelstitel tragen, in der britischen protokollarischen Rangordnung vor allen anderen Peers stehen und nicht anhand ihres Adelstitels eingeordnet werden.
