The IMU Executive Committee consists of ten voting members elected for four-year terms: the four officers (President, two Vice-Presidents, and Secretary General) and six Members-at-Large. The IMU General Assembly 2006 in Santiago de Compostela increased the number of members-at-large from five to six. The retiring president is an ex-officio member of the IMU Executive Committee without vote for a period of four years.

The current members (term January 1, 2023 to December 31, 2026) of the IMU Executive Committee are listed below. The above photo (credit: Christoph Assmann) was taken on the occasion of the first meeting of the current term, held in March 2023 at the IMU Secretariat in Berlin, Germany.
