The purpose of this article is to describe the possible futures of French museums up to 2030. To do this we rely on a Delphi study that took place between late 2017 and early 2018 with 99 experts from the field. We propose three scenarios. The first aims to create museums centered around youth and to democratize culture. The second corresponds to the reaction of museums facing a decrease in public funding. The third is a breakdown scenario, where museums undergo evolutions. In this latter scenario, a direct participation of nearby stakeholders is observed, unlike the other two scenarios.
