METROPOLIS, World Association of the Major Metropolises, is the leading international organization that gathers cities and metropolitan regions with more than a million inhabitants.

Created in 1985, the METROPOLIS Association is represented by more than 130 members from across the world and operates as an international forum for exploring issues and concerns common to all big cities and metropolitan regions. Metropolis also manages the Metropolitan Section of United Cities and Local Governments (UCLG).  

For more than 30 years, METROPOLIS has had the mission of accompanying cities in mutual learning, innovation, governance, technical and financial assistance, international presence and debate.


In metropolitan governance, understood as collaboration between metropolitan governments on the one hand and the other levels of local, regional and state governments on the other; public/private cooperation and public participation.

In technical/financial assistance, to mobilize new financial resources for investments marked at sustainable and efficient development.

In mutual learning, as a result of the transfer of knowledge, practices and experiences between metropolitan governments and their associates

In innovation, understood as a result of collaboration between city governments and groundbreaking businesses and entities in the management of urban issues.

In presence in international forums and the defense of city interests and concerns.

In the debate about ideas on city trends and evolution.


METROPOLIS wishes to build a network of Initiatives among metropolitan governments and their collaborating partners to promote projects in partnership for urban sustainability, understood simultaneously in its environmental, economic, social, and cultural aspects.

Take the Initiative!


METROPOLIS will consider the following over the current period:

  • Represent and give international political visibility to metropolitan interests
  • Promote reflection on trends in the evolution of cities
  • Find innovative solutions to metropolitan problems
  • Contribute to metropolitan governance to reduce metropolitan imbalances
  • Promote financial and technical assistance to metropolitan areas in developing countries
