The International Micropatrological Society (IMS) was an American learned society and research institute dedicated to the study of micronations. Founded in 1973 by Frederick W. Lehmann IV of St. Louis, Missouri, the IMS coined micropatrology as the study of micronations and micronationalism. It had documented 128 micronations and similar political entities by 1976.

The IMS assessed the legitimacy of micronational claims in five categories—B ("bogus"), E ("extinct"), F ("fiction"), T ("traditional") and O ("other"); according to the IMS, only micronations rated T or O had good chances of achieving independence. Owned by Lehmann and Christopher Martin, the IMS had offices in St. Louis, Missouri and King's Lynn, Norfolk, England. According to the Yearbook of International Organizations, the IMS was disestablished in 1988.
