List of political families in the United Kingdom

During its history, the United Kingdom (and previously the Kingdom of England, Kingdom of Scotland and Kingdom of Ireland) has seen many families who have repeatedly produced notable politicians, and consequently such families have had a significant impact on politics in the British Isles.

Certain families, such as the Cecils, owe their long-standing political influence to the composition and role of the House of Lords, which was still mainly composed of hereditary legislators until the passing of the House of Lords Act 1999. Other families, such as the Longs, have had a long tradition of standing for elected office, usually in the House of Commons. Many such families were part of the landed gentry, who often exerted political control in a certain locality over many generations.
