美国地理学协会（英语：American Geographical Society，缩写：AGS）是美国的一个从事地理学相关职业人士参加的组织。于1851年创建于纽约市。协会的大多数会员都是美国人，但也有相当数量的外国人会员。协会的目标是提高地理学知识研究水准，并且通过普及和运用地理学知识，让非地理学者，特别是政策决定者能够理解并应用地理学知识。美国地理学协会是美国历史最长的全国规模的地理学团体。在其一个半世纪的历史中，美国地理学协会特别关注北极、南极、拉美三个地区。美国地理学协会的显著特征之一是学会对探险活动进行支持的前提是该探险必须取得明确的科学业绩。

The American Geographical Society (AGS) is an organization of professional geographers, founded in 1851 in New York City. Most fellows of the society are Americans, but among them have always been a significant number of fellows from around the world. The Society encourages activities that expands geographical knowledge, and the interpretation of that knowledge so that it can be useful to geographers and other disciplines, especially in a policymaking environment. It is the oldest nationwide geographical organization in the United States. Over the century and a half of its existence, the AGS has been especially interested in three regions: the Arctic, the Antarctic, and Latin America. A signature characteristic of the AGS-sponsored exploration was the requirement that its expeditions produce tangible scientific results.
