HUN-REN Wigner Fizikai Kutatóközpont (HUN-REN Wigner FK)

A HUN-REN Wigner FK 2012. január 1-től a korábbi MTA KFKI Részecske- és Magfizikai Kutatóintézet és a korábbi MTA Szilárdtestfizikai és Optikai Kutatóintézet egyesülésével jött létre. Jelenleg a Magyar Kutatási Hálózat legnagyobb fizikával foglalkozó kutatóközpontja, illetve a Magyar Tudományos Akadémia Kiválósági Kutatóközpontja. 2013-tól a Kutatóközpont részeként működik a világszínvonalú Wigner Adatközpont is.
