Meyrin is a municipality of the Canton of Geneva, Switzerland.
The main site of CERN, the European particle physics research organisation, is in Meyrin. Meyrin was originally a small agricultural village until the 1950s, when construction of CERN began just to the north. It is now a commuter town dominated with apartment high-rises, and many of its residents work at CERN or in central Geneva. Geneva International Airport is partially located within Meyrin.
