The 1900 United Kingdom general election in Ireland was held in September and October 1900. Ninety-nine of the seats were in single-member districts using the first-past-the-post electoral system, and the constituencies of Cork City and Dublin University were two-member districts using block voting.

The Irish Parliamentary Party was formed in 1874 by Isaac Butt, the leader of the Nationalist Party, replacing the Home Rule League, as official parliamentary party for Irish nationalist Members of Parliament (MPs) elected to the House of Commons at Westminster within the United Kingdom of Great Britain and Ireland up until 1918. Its central objectives were legislative independence for Ireland and land reform. Its constitutional movement was instrumental in laying the groundwork for Irish self-government through three Irish Home Rule bills.
