Ennis (Parliament of Ireland constituency)

Ennis was a constituency represented in the Irish House of Commons until 1800, the lower house in the Irish Parliament of the Kingdom of Ireland. In the Patriot Parliament summoned by James II in 1689, Ennis was represented with two members. Following the Acts of Union 1800, it was succeeded by the Ennis constituency in the United Kingdom House of Commons.

By 1783, the seat was in the control of the O'Brien and Burton families. Notable members include Sir Edward O'Brien, 4th Baronet. When his son, the Tory turned Irish rebel, William Smith O'Brien, became MP for the then UK Parliamentary seat of Ennis, The Times described the constituency as "his father's borough".
