The Curragh incident of 20 March 1914, sometimes known as the Curragh mutiny, occurred in the Curragh, County Kildare, Ireland. The Curragh Camp was then the main base for the British Army in Ireland, which at the time still formed part of the United Kingdom of Great Britain and Ireland. Ireland was scheduled to receive a measure of devolved government, which included Ulster, later in the year. The incident is important in 20th-century Irish history, and is notable for being one of the few occasions since the English Civil War in which elements of the British military openly intervened in politics. It is widely thought of as a mutiny, though no orders actually given were disobeyed.

The Curragh is a flat open plain of almost 2,000 hectares of common land in County Kildare. This area is well known for Irish horse breeding and training. The Irish National Stud is located on the edge of Kildare town, beside the Japanese Gardens. Also located here is Pollardstown Fen, the largest fen in Ireland. This area is of particular interest to botanists and ecologists because of the numerous bird species that nest and visit there. There are also many rare plants that grow there.
