The Madrid system 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 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. The Madrid Protocol system provides for the international registration of trademarks 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. Adherence to the protocol includes membership of the Madrid Union. As of April 2016 there are 97 members:
