Erasmus Student Network - ESN Politecnico Milano is a non-profit, apolitical association of students founded in 1992. Its aim is to support the student exchange programs, supplying information and any kind of help that can be voluntarily given by its members.

ESN Politecnico is member of the Italian network, ESN Italia, and of the international one, ESN International, since December 1994. ESN International is a pan-European student organisation which was founded in Copenhagen in 1990. Since then, the network has expanded considerably. At the moment ESN consists of more than 250 sections in 30 countries. Despite its name, the network is devoted to students participating in all exchange programmes in Europe.

ESN Politecnico Milano is the local section based in Politecnico di Milano (Italy).
