Mediterranean Shipping Company S.A, branded as MSC, is an international shipping line founded by Gianluigi Aponte in Italy in 1970. The company is owned by the Aponte family with its headquarters in Switzerland since 1978. It is the world's largest container shipping company by both fleet size and cargo capacity, controlling about 19.7 percent of the global container ship fleet.

A container ship is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.
