联合国托管理事会是联合国负责监督托管领土行政管理的机构，成立于1945年。成立托管制度的目的是为了进行去殖民，使托管领土朝自治或独立的方向发展，尊重托管领土居民的自决。被托管的国家大多是国际联盟时期的委任统治地，或是第二次世界大战期间被轴心国军事占领的地区（例如朝鲜半岛）。

在最后一个托管领土帕劳于1994年10月独立并成为联合国成员国后，联合国托管理事会已经完成其历史使命，暂停运作。但由于明载于《联合国宪章》，托管理事会仍继续「存在」，其正式结束运作须俟《联合国宪章》之修订。

The United Nations Trusteeship Council (French: Le Conseil de tutelle des Nations unies), one of the principal organs of the United Nations, was established to help ensure that trust territories were administered in the best interests of their inhabitants and of international peace and security. The trust territories—most of them former mandates of the League of Nations or territories taken from nations defeated at the end of World War II—have all now attained self-government or independence, either as separate nations or by joining neighbouring independent countries. The last was Palau, formerly part of the Trust Territory of the Pacific Islands, which became a member state of the United Nations in December 1994.
