Astroparticle physics is the field at the intersection of particle physics, astronomy and cosmology. It addresses questions like “What is dark matter?” “Do protons live forever?” “What are the properties of neutrinos and how did they shape our Universe?”, “What is the origin of cosmic rays?” or “What will we learn from gravitational waves?”. The field has grown close to technical maturity and undergoes a rapid development, with fascinating discoveries made or just ahead. With cost of next generation experiments on the 100 MEuro scale, a coherent approach and worldwide cooperation is mandatory. A European Roadmap on Astroparticle has been worked out by ApPEC (Astroparticle Physics European Coordination). The talk will review the field and present the main findings and recommendations of the roadmap.
