The Roman Catholic Relief Act 1829 gives Roman Catholics in the United Kingdom the right to vote and to sit in Parliament.

The Roman Catholic Relief Act 1829, also known as the Catholic Emancipation Act 1829, was an act of the Parliament of the United Kingdom that removed the sacramental tests that barred Roman Catholics in the United Kingdom of Great Britain and Ireland from Parliament and from higher offices of the judiciary and state. It was the high point of a fifty-year process of Catholic emancipation which had offered Catholics successive measures of "relief" from the anti-Catholic civil and political disabilities imposed by Penal Laws in both the Kingdom of Great Britain and the Kingdom of Ireland in the seventeenth and early eighteenth centuries.
