国际联盟托管地是指根据1919年6月28日签订的《国际联盟规约》的第22条而成立的一些区域。当这条目在1945年末收纳到联合国宪章之后，所有国联的托管地（除了西南非洲，即今纳米比亚），都转为联合国的托管领地，这之前被雅尔达会议所同意。

除了托管地外，国联本身亦曾直接管治萨尔15年，后来经该地区全民公决回归德国。此外，国联亦于1920年11月15日至1939年9月1日管治但泽自由市（今波兰格但斯克，德文仍称但泽）。

A League of Nations mandate was a legal status for certain territories transferred from the control of one country to another following World War I, or the legal instruments that contained the internationally agreed-upon terms for administering the territory on behalf of the League. These were of the nature of both a treaty and a constitution, which contained minority rights clauses that provided for the rights of petition and adjudication by the International Court. The mandate system was established under Article 22 of the Covenant of the League of Nations, entered into on 28 June 1919. With the dissolution of the League of Nations after World War II, it was stipulated at the Yalta Conference that the remaining Mandates should be placed under the trusteeship of the United Nations, subject to future discussions and formal agreements. Most of the remaining mandates of the League of Nations (with the exception of South-West Africa) thus eventually became United Nations Trust Territories.
