Progressive International (PI) is a left-wing political international with over 70 member groups, including trade unions, political parties, peasant organisations, and social movements. It has been described as a "worldwide anti-capitalist organisation."

The Progressive International was formally founded and launched on 11 May 2020, responding to a 2018 open call by the Democracy in Europe Movement (DiEM25) and The Sanders Institute for progressive forces to form a unified front. The open call was echoing two twinned appeals published in 2018 by U.S. Senator Bernie Sanders and former Greek minister of finance Yanis Varoufakis to form an international movement to combat the rise of authoritarianism represented by Donald Trump .

The founding was supported by a council of over 40 advisors including Ece Temelkuran, Katrín Jakobsdóttir, Yanis Varoufakis, Carola Rackete, Nick Estes, Vanessa Nakate, Noam Chomsky, Arundhati Roy, Naomi Klein, Niki Ashton, Rafael Correa, Fernando Haddad, Celso Amorim, and Alvaro Garcia Linera.

The International claims to counter what it calls the resurgence of authoritarian nationalism worldwide as well as the rise of disaster capitalism. As its mission, the Progressive International aims to "unite, organize and mobilize the world's progressive forces."

The Progressive International is guided by an advisory Council that sets the organisation's political and strategic direction. The Secretariat, which includes translators, web developers, graphic designers, policy analysts, and community organisers oversees the day-to-day organisational operations, separated into several thematic areas: Movement, Blueprint, Wire, and Observatory.

The Cabinet serves as the main executive organ responsible for development, planning, and staffing decisions. The Cabinet draws its membership from the other two bodies, consisting of eight Council members: Srećko Horvat, Aruna Roy, Pierre Sané, Fatima Diallo, Rachmi Hertanti, Julian Aguon, Renata Ávila and Scott Ludlum, as well as general coordinators David Adler and Varsha Gandikota-Nellutla.

In October 2020, Progressive International said that it was "particularly concerned about the integrity of the presidential elections in Bolivia" and sent an observer group made up of Members of Parliament from around Europe to observe the election.

On 15 November 2021, the Progressive International launched their global observatory "as attacks on democracy escalate across the world" and "authoritarian leaders are getting organised to capture the courts, criminalise opposition, and rig the rules to hold onto power," said General Coordinator David Adler in a statement.
