The American Center for Mongolian Studies (ACMS; Mongolian: Америкийн Монгол Судлалын Төв) is a US registered 501(c)3 not-for-profit, academic organization which promotes research and scholarship in Inner Asia, a broad region consisting of Mongolia and parts of China, Russia and Central Asia, including Inner Mongolia, Xinjiang, Buryatia, Tuva and eastern Kazakhstan.

International academic activities in Inner Asia are often conducted within the confines of particular disciplines because opportunities for discussing and sharing cross-discipline research are rare.

The American Center for Mongolian Studies was established in order to facilitate and coordinate the various multi-discipline research activities occurring each year in the region.

Mongolian Studies scholars and discipline based Mongolian researchers were instrumental in the establishment of the ACMS, and the United States Department of Education, United States Embassy in Mongolia, and Council for American Overseas Research Centers (CAORC) contributed significant financial resources to establish and operate the ACMS Mongolia office.

In November 2013 the ACMS Mongolia office moved to its current location inside the East Entrance of Natsagdorj Library in Ulaanbaatar.

It organizes and conducts international conferences, provides fellowships to student researchers, cooperates with local libraries to improve access to materials, and produces informational resources about academic activities in Inner Asia.

In addition, it organizes regular public lectures, the Speaker Series, in Ulaanbaatar which are given by Mongolian and international scholars on various research topics.

The ACMS was founded with the intention of providing the institutional support to address these resources issues and organize research produced in the region.
