About Trinity College Dublin

Basic information and contact details for Trinity College Dublin

Founded in 1592, Trinity College Dublin, the University of Dublin, is Ireland’s leading university, ranked number one in Ireland by Times Higher Education. 

Located in the heart of Dublin, Trinity is home to more than 22,000 undergraduate and postgraduate students, offering an inclusive, comprehensive education across three faculties: Arts, Humanities and Social Sciences; Science, Technology, Engineering and Mathematics (STEM); and Health Sciences.

Curiosity-driven research 

Trinity is internationally recognised for its strengths in Health and Life Sciences; Artificial Intelligence and Digital Technologies; Climate and Sustainability; Culture, Heritage and the Humanities; and research addressing major global societal challenges. 

We champion curiosity-driven research, recognising its power to transform lives, shape societies and deliver long-term impact. 

We harness our collective expertise for the greater good through five research institutes and a wide range of research centres across multiple academic disciplines. Trinity hosts two of the seven new Research Ireland-funded Rinn centres, Rinn Quantum and Rinn Advanced Therapies, with combined funding of approximately €90 million. We are also one of five coordinating institutions in a third, Rinn Artificial Intelligence, and our researchers are principal investigators in the other four. 

The Trinity Long Room Hub Arts & Humanities Research Institute brings scholars, the public, policymakers and political leaders together. Through research, creativity and critical thinking, it explores how the arts and humanities can strengthen democracy and shape the future.

This rich environment informs our research-led teaching, ensuring that students learn from academics who are advancing knowledge in their fields.

Ranked as the 24th most international university in the world by Times Higher Education, we welcome students and staff from 131 countries, making our campus truly diverse and international. Our alumni network involves 170,000 alumni from 150 countries.
