The Paris Peace Forum (French: Forum de Paris sur la Paix) is a French non-profit organisation created in March 2018. The organisation hosts an annual gathering of world leaders and heads of international organisations, as well as leaders from civil society and private sectors and thousands of individuals from around the globe, on creating forms of collective action. The Paris Peace Forum completes the existing world agenda of multilateral gatherings by creating a specific event for global governance issues, as economic and financial issues are dealt at the World Economic Forum in Davos, and security issues at the Munich Security Conference.

The forum's purpose is to be inclusive and solution-oriented. With this in mind, the forum showcases projects each year, coming from all around the world, which display concrete and efficient solutions to governance challenges. Focused on concrete initiatives, the annual event has been used as a platform for the launch of important, multi-actor initiatives, such as the B4IG coalition or the Paris Call for Trust and Security in the Cyberspace.

In a world requiring more collective action, the Paris Peace Forum is a platform open to all seeking to develop coordination, rules, and capacities that answer global problems. Its three primary pillars of activity include year-round policy initiatives and project support activities coupled by an annual event in November:

The Paris Peace Forum was founded in 2018 by Justin Vaïsse, as he was director for Policy Planning at the French Ministry for Europe and Foreign Affairs, to tackle global problems and strengthen multilateral cooperation. Soon after the first edition, Pascal Lamy was appointed President of the Paris Peace Forum, and Justin Vaïsse became its director general. The first edition was hosted in November 2018 at the Grande halle de la Villette.

The eighth and most recent edition of the Paris Peace Forum was held on 29-30 October at the Palais de Chaillot.

The Paris Peace Forum was born out of the principle that "a badly governed world would quickly become a world at war", as explained by Justin Vaïsse, then president of the forum. At the Meeting of Ambassadors on 29 August 2017, French President Emmanuel Macron spoke of the fact that peace is not something to be taken for granted, mentioning the Syrian Civil War and the Russo-Ukrainian War as examples. In light of such developments, he called for the need to take concrete steps to strengthen multilateralism and preserve peace. Macron then announced the creation of the Paris Peace Forum on 4 January 2018.

The purpose of the forum is to commemorate Armistice Day, as well as to "reflect together, propose concrete initiatives, reinvent multilateralism and all forms of contemporary cooperation". President Macron and then-president Justin Vaïsse aimed at bringing together global governance actors, in an international and open space, in order to interact, discuss and generate concrete solutions. An important aspect of the forum is the showcasing of projects from around the world. Each of these projects proposes an innovative solution to a specific issue.

During the forum, ten projects are selected as Scale-up projects to receive mentorship and support from the Paris Peace Forum for a one-year period.
