There were four Irish Home Rule Bills in the late 19th and early 20th centuries, to reverse parts of the 1801 Act of Union. Only two were passed by the Parliament of the United Kingdom and one of these was never enacted. They were:

• 1886: First Irish Home Rule Bill defeated in the House of Commons and never introduced in the House of Lords.
• 1894: Second Irish Home Rule Bill passed the House of Commons, but defeated in the House of Lords.
• 1914: Third Irish Home Rule Bill passed but 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 (Government of Ireland Act 1920)
