Forschungszentrum Jülich GmbH is a national research institution in Germany that pursues research in the fields of energy, information, and bioeconomy. Its focus is supercomputers, but also other research priorities includes structural change in the Rhineland lignite-mining region, hydrogen, and quantum technologies. It was first established as The Society for the Promotion of Nuclear Physics Research (GFKF), and was later renamed Nuclear Research Centre Jülich (KFA, taken from the German "Kernforschungsanlage Jülich"). It was converted into a limited liability company (GmbH) seven years later, and in 1990 was renamed Forschungszentrum Jülich GmbH, which fell in line with its research shifting away from nuclear physics.

It is headquartered in the town of Jülich outside of Cologne, Germany.

The partners of Forschungszentrum Jülich are the Federal Republic of Germany (90%) and the federal state of North Rhine-Westphalia (10%).
