Covering research, technology, medicine, energy, and business, Vienna's 2026 meeting calendar offers impressive proof of the city's position as one of the world’s leading meeting destinations. Numerous international flagship congresses and pioneering corporate events will take place throughout the year – many of them welcoming several thousand participants.

Topics range from geosciences and space research to health economics, fetal medicine, robotics, telecommunications, and AI. Alongside globally established formats such as the European Congress of Radiology (ECR) and the General Assembly of the European Geosciences Union (EGU) - both long-standing in Vienna - several new events will debut in the city in 2026, including the international High End trade fair and the World Congress in Fetal Medicine.

With outstanding infrastructure, global accessibility, a professional environment that guarantees reliability and quality, and its unique combination of international outlook and high urban quality of life, Vienna offers ideal conditions for successful events - and a platform for innovation, collaboration, and cross-sector dialogue.
