The General Assembly 2026 of the European Geosciences Union (EGU) will take place at the Austria Center Vienna (ACV) in Vienna, Austria and online from 3 - 8 May 2026.

The EGU General Assembly 2026 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience.
