The European Strategy for Particle Physics provides a clear prioritisation of European ambitions in advancing the science of particle physics. It takes into account the worldwide particle physics landscape and developments in related fields, and is initiated by the CERN Council to coordinate activities across a large, international and fast-moving community with the aim of maximising scientific returns.

The latest process for the Update of the Strategy was launched by the CERN Council on September 27, 2018. It was concluded on June 19, 2020 when the CERN Council unanimously adopted the resolution to update the European Strategy for Particle Physics.
