A multinational corporation (MNC) or multinational enterprise (MNE) is a corporate enterprise that manages production or delivers services in more than one country.

A MNC differs slightly from a transnational corporation (TNC), because while MNC's are traditionally national companies with foreign subsidiaries, a TNC does not identify itself with one national home. However, these terms are often used interchangeably. Multinational corporations can have a powerful influence in local economies, and even the world economy.
