The Jews Relief Act 1858 (21 & 22 Vict. c. 49), also called the Jewish Disabilities Act, is an Act of the Parliament of the United Kingdom which removed previous barriers to Jews entering Parliament, a step in Jewish emancipation in the United Kingdom.
Following the Roman Catholic Relief Act 1829 there had been an unsuccessful attempt in 1830 to also allow Jews to sit in Parliament. The 1858 measure was the result of a long process which began with a bill introduced by the Whig leader Lord John Russell following the election of Lionel de Rothschild to the City of London constituency in 1847. Rothschild could not take the seat without taking the Christian oath of office.
