The University of Patras is a member of the European Universities Association (EUA). The EUA is a major association that formulates and suggests policy measures regarding Higher Education Institutions. UP is also member of the Santander Group, a powerful network constantly providing opportunities for members to expand their horizons in inter-university co-operations.

The UP has also joined the European University Continuing Education Network (EUCEN), Black Seas Universities Network (BSUN) and University Network of the European Capitals of Culture (UNECC). The external window to Mediterranean countries is created by the establishment of bilateral agreements, membership in the Community of Mediterranean Universities (CMU), in the Reseau Mediterraneen des Ecoles d’Ingenieurs and in the Euromed Permanent University Forum. The UNIADRION Network, on the other hand, promotes co-operation opportunities between the UP and Universities of neighbouring countries. Academic staff members are also encouraged to join Scientific Networks in their field of study and research such as the Association of European Schools of Planning (AESOP) and the European Chemistry Thematic Network (ΕCTN). The UP has finally adopted the Magna Charta Observatory of Fundamental University Values and Rights.
