A potwalloper (sometimes potwalloner or potwaller) is an archaic term referring to a borough constituency returning members to the British House of Commons before 1832 and the Reform Act created a uniform suffrage. (Several potwalloper constituencies were also represented in the Irish House of Commons, prior to its abolition in 1801). A potwalloper borough was one in which a householder had the right to vote if he had, in his house, a hearth large enough to boil, or wallop, a cauldron, or pot.
