The University of Geneva is a public research university located in Geneva, Switzerland. It was founded in 1559 by John Calvin as a theological seminary and law school.

Today, the university is the third largest university in Switzerland by number of students. In 2009, the University of Geneva celebrated the 450th anniversary of its founding. Almost 40% of the students come from foreign countries.
