The Institute of Materials Science of Barcelona​ (ICMAB) is a Severo Ochoa Centre of Excellence research center which beongs to the Consejo Superior de Investigaciones Científicas (CSIC) and is governed by a Foundation board.

The Institute was set up in 1987 and subsequently, in April 1991, the laboratories were opened at the Campus of the Autonomous University of Barcelona (UAB). It is part of the Barcelona Nanotechnology Cluster in Bellaterra.

The aim of the institute is to carry out research aimed at obtaining and characterising materials of industrial interest. Its activities are based on the synthesis, preparation, crystallization and characterisation of functional high-performance materials and nanomaterials, which in some cases have led to the construction of device prototypes based on these materials.
