International University Audentes (IUA; Estonian: Rahvusvaheline Ülikool Audentes) was Estonia's largest private university, situated in the country's capital city Tallinn.

The programs are offered in three languages - English, Estonian and Russian.

All programs on bachelor, master and doctoral levels are compiled considering the international perspective and requirements.

By the 2007/08 academic year IUA had bilateral agreements with 44 universities in Europe.

Since then studies in Estonian and Russian have been promoted under the name Audentes University and studies in English under the name International University Concordia Audentes.
