The France–Ireland relations refers to the diplomatic relations between the French Republic and the Republic of Ireland. France and Ireland are both members of the Council of Europe, European Union and the Organisation for Economic Co-operation and Development.
 France and Ireland have a long history of relations given the proximity between Ireland and France. There has always been migration back and forth between the two since ancient times. In 1578, the Irish College in Paris was established as a Catholic school to train Irish students. In 1689, France supported Ireland during the Williamite War to restore King James II of England to the throne. After the Treaty of Limerick, for the next hundred years, the French Army would include an Irish Brigade in its army. The Irish who fought for France (and other foreign nations) would come to be known as Wild Geese. Many Irish soldiers also traveled and served with the French in the exploration and colonization of New France.
 In 1796, inspired by the French Revolution, the Society of United Irishmen began an uprising against British rule in Ireland which became known as the Irish Rebellion of 1798 and was led by Irish revolutionary fighter Wolfe Tone. France supported the Irish rebellion and, in December 1796, sent its Expédition d'Irlande of 12,000 soldiers to Bantry Bay, County Cork; however, the soldiers were not able to land as there were 40,000 British troops in the area waiting for them. In August 1798, a French fleet landed in Killala Bay, County Mayo with 1,060 soldiers under the command of General Jean Joseph Amable Humbert. Irish rebels joined the French against the British but lost at the Battle of Ballinamuck in September 1798. The Irish rebels were executed while the surviving French soldiers were repatriated. The aftermath of the fight became known as Bliain na bhFrancach (The Year of the French). In 1803, Napoléon Bonaparte created the Irish Legion which fought for France in the Walcheren Campaign and Peninsular War. The legion was disbanded in 1815. In 1873, Patrice de MacMahon became the first French President of Irish descent.
 As part of the British Empire, Irish soldiers fought in France during World War I (1914-1918) and Irish troops fought in the Battle of the Somme. In 1922, the Irish Free State obtained its independence from the United Kingdom. In 1929, Ireland opened a diplomatic legation in Paris and appointed Gerald Edward O'Kelly de Gallagh et Tycooly as the first Irish Minister to France. In 1930, France opened its first diplomatic legation in Dublin. During World War II (1939-1945) Ireland remained officially neutral. Approximately 50 Irish men and women joined the French Resistance, such as Irish writer Samuel Beckett. After the war, both nations upgraded their diplomatic legations to embassies.
 In 1969, French President Charles de Gaulle paid an official visit to Ireland and met with Irish President Éamon de Valera. Since the establishment of diplomatic relations, relations between France and Ireland have been close and both nations have worked together within the European Union. France is Ireland's fourth largest tourism market. 9,000 French citizens reside in Ireland and 15,000 Irish citizens reside in France. Ireland is an observer member of La Francophonie.
