The Irish Volunteers (Irish: Óglaigh na hÉireann), sometimes called the Irish Volunteer Force or Irish Volunteer Army, was a military organisation established in 1913 by Irish nationalists. It was ostensibly formed in response to the formation of the Ulster Volunteers in 1912, and its declared primary aim was "to secure and maintain the rights and liberties common to the whole people of Ireland". The Volunteers included members of the Gaelic League, Ancient Order of Hibernians and Sinn Féin, and, secretly, the Irish Republican Brotherhood (IRB). Increasing rapidly to a strength of nearly 200,000 by mid-1914, it split in September of that year over John Redmond's commitment to the British War effort, with the smaller group retaining the name of "Irish Volunteers".

Home Rule for Ireland dominated political debate between the two countries since Prime Minister William Ewart Gladstone introduced the first Home Rule Bill in 1886, intended to grant a measure of self-government and national autonomy to Ireland, but which was rejected by the House of Commons. The second Home Rule Bill, seven years later having passed the House of Commons, was vetoed by the House of Lords. It would be the third Home Rule Bill, introduced in 1912, which would lead to the crisis in Ireland between the majority Nationalist population and the Unionists in Ulster.

On 28 September 1912 at Belfast City Hall just over 450,000 Unionists signed the Ulster Covenant to resist the granting of Home Rule. This was followed in January 1913 with the formation of the Ulster Volunteers composed of adult male Unionists to oppose the passage and implementation of the bill by force of arms if necessary. The establishment of the Ulster Volunteers was (according to Eoin MacNeill) instigated, approved, and financed by English Tories with the other major British party, the Liberals, not finding "itself terribly distressed by that proceeding."
