The four Irish Home Rule bills introduced in the House of Commons of the United Kingdom during the late 19th and early 20th centuries, were intended to grant self-government and national autonomy to the whole of Ireland within the United Kingdom of Great Britain and Ireland and reverse parts of the Acts of Union 1800. Of the two that passed the Parliament of the United Kingdom the Third Bill, enacted as the Government of Ireland Act 1914 and then suspended, while the Fourth Bill, enacted as the Government of Ireland Act 1920 established two separate Home Rule territories in Ireland, of which the one was implemented by the Parliament of Northern Ireland, but the second Parliament of Southern Ireland was not implemented in the rest of Ireland. The bills were:

1886: First Irish Home Rule Bill defeated in the House of Commons and never introduced in the House of Lords.
1893: Second Irish Home Rule Bill passed the House of Commons, but defeated in the House of Lords.
1914: Third Irish Home Rule Act passed with Royal Assent never came into force, due to the intervention of World War I (1914–18) and of the Easter Rising in Dublin (1916).
1920: Fourth Irish Home Rule Act (replaced Third Act, passed and implemented as the Government of Ireland Act 1920) which established Northern Ireland as a Home Rule entity within the United Kingdom of Great Britain and Northern Ireland and simultaneously resulted in the partition of Ireland.
