ECRIN (European Clinical Research Infrastructure Network) is a not-for-profit intergovernmental organisation that provides support for the development and implementation of multinational clinical research projects in Europe. These are mostly investigator initiated (rather than industry sponsored) clinical trials, run by non-commercial Clinical Trials Units (CTUs) based within universities or hospitals, though ECRIN does also support trials initiated by biotech and medical device small and medium enterprises (SMEs).

ECRIN currently has seven Member Countries (Czech Republic, France, Germany, Hungary, Italy, Norway, Portugal and Spain) and two Observer Countries (Switzerland and Slovakia). It has the legal status of a European Research Infrastructure Consortium (ERIC) with its headquarters in Paris, working  with a ‘European Correspondent’ (EuCo) in each Member and Observer Country.
