The Siege of Jadotville is a 2016 action-war film directed by Richie Smyth and written by Kevin Brodbin. An Irish-South African production, the film is based on Declan Power's book, The Siege at Jadotville: The Irish Army's Forgotten Battle (2005), about an Irish Army unit's role in the titular Siege of Jadotville during the United Nations Operation in the Congo in September 1961, part of the Congo Crisis that stretched from 1960 to 1965.

As part of the larger Congo Crisis (1960–64), the siege of Jadotville began on 13 September 1961, lasting for five days. While serving under the United Nations Operation in the Congo, a small contingent of the Irish Army's 35th Battalion, designated "A" Company, were besieged at the UN base near the mining town of Jadotville by Katangese forces loyal to the secessionist State of Katanga. The siege took place during the seven-day escalation of hostilities between ONUC and Katangese forces during Operation Morthor. Although the contingent of 155 Irish soldiers repelled attacks by a 3,000-strong Katangese force, they were eventually forced to surrender after running out of ammunition and water. "A" Company was subsequently held as prisoners of war for approximately one month, before being released on 15 October as part of a prisoner exchange. The Irish forces inflicted approximately 1,300 casualties on the Katangan force, with no deaths amongst "A" Company.
