This constituency was a parliamentary borough based in the town of Baltimore in County Cork.
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.
[1] In the Patriot Parliament of 1689 summoned by King James II, Baltimore was represented with two members.
