Middle East Medievalists (MEM) is an international professional non-profit association of scholars interested in the study of the Islamic lands of the Middle East during the medieval period (defined roughly as 500-1500 C.E.). MEM officially came into existence on 15 November 1989 at its first annual meeting, held in Toronto. MEM is incorporated in the state of Illinois; contributions to MEM are considered exempt from federal income tax by the United States Internal Revenue Service.

MEM has two primary goals. The first is to increase the representation of medieval scholarship at scholarly meetings in North America and elsewhere by co-sponsoring panels. The other principal objective of MEM is to foster communication among individuals and organizations with an interest in the study of the medieval Middle East. MEM also hopes, in the future, to advance the study of the medieval Middle East by undertaking such projects as scholar exchanges, conferences, etc.

As part of its effort to promote scholarship and facilitate communication among its members, MEM publishes Al-ʿUsur al-Wusta: The Journal of Middle East Medievalists.

MEM conducts its business meeting annually in the autumn, normally in conjunction with the meeting of the Middle East Studies Association (MESA), which is usually held in November. The general business meeting is open to all current members of MEM and to those considering membership. The Board of Directors of MEM is elected annually at the general business meeting, or by mail ballot.
