CIM (International Center for Mathematics) is a not-for-profit, privately-run association that aims at developing and promoting research in Mathematics. At present CIM has 41 associates, including 13 Portuguese Universities, the University of Macau, 23 Research Centres and Institutes, the Portuguese Mathematical Society (SPM), the Portuguese Operational Research Society (APDIO), the Portuguese Statistical Society (SPE) and the Portuguese Association of Theoretical, Applied and Computational Mechanics (APMTAC).

CIM was formally set up on the 3rd of December, 1993 and was launched as a national project to involve all Portuguese mathematicians. During the past years, CIM has organized several meetings in mathematics and many interdisciplinary conferences. As a result, CIM has become an important forum for national and international cooperation among mathematicians and other scientists. CIM is also a privileged place for the exchange of information among Portuguese researchers and scientists from Portuguese-speaking countries.

CIM is managed by a Board of Directors elected by the associates in the General Assembly. The Board of Directors organizes the annual scientific program, which is submitted for advice to the Scientific Council. This committee includes a number of national and international prestigious mathematicians that are invited by the Board of Directors and approved by the General Assembly.
