The Madrid system (officially the Madrid system for the international registration of marks) is the primary international system for facilitating the registration of trademarks in multiple jurisdictions around the world. Its legal basis is the multilateral treaty Madrid Agreement Concerning the International Registration of Marks of 1891, as well as the Protocol Relating to the Madrid Agreement (1989).

The Madrid system provides a centrally administered system of obtaining a bundle of trademark registrations in separate jurisdictions. Registration through the Madrid system does not create a unified registration, as in the case of the European Union trade mark system; rather, it creates a bundle of national rights through an international registration able to be administered centrally. Madrid provides a mechanism for obtaining trademark protection in many countries around the world which is more effective than seeking protection separately in each individual country or jurisdiction of interest.

The Madrid Protocol system provides for the international registration of trade marks by way of one application that can cover more than one country. The opportunity of having a single registration to cover a wide range of countries gives advantages, both in terms of portfolio management and cost savings, as opposed to a portfolio of independent national registrations.

Madrid now permits the filing, registration and maintenance of trade mark rights in more than one jurisdiction, provided that the target jurisdiction is a party to the system. The Madrid system is administered by the International Bureau of the World Intellectual Property Organization (WIPO) in Geneva, Switzerland. There
