A Public Scientific and Technical Research Establishment (French: Établissement public à caractère scientifique et technologique, EPST) is a category of public research institutes. In France, they were authorized by Law No. 82-610 of 15 July 1982. In Algeria, they were authorized by decree No. 99-256 of 16 November 1999.
A research collaboration between an EPST and a university laboratory is called a mixed research unit (Unité mixte de recherche or UMR).
