Sorbonne University (French: Sorbonne Université) is a public research university located in Paris, France. The institution's legacy reaches back to the Middle Ages in 1257 when the College of Sorbonne was established by Robert de Sorbon as a constituent college of the University of Paris, one of the first universities in Europe. Its current iteration was formed in 2018 by the merger of Paris-Sorbonne University (Paris IV) and the Université Pierre et Marie Curie (Paris VI).

Sorbonne University is one of the most sought after universities by students and researchers from France, Europe, and the French speaking countries. Most notably, Marie Skłodowska-Curie, who came from Poland in 1891 and joined the Faculty of Sciences of the University of Paris, was also the first woman to become a professor at the Sorbonne. Marie Curie and her husband Pierre Curie are considered the founders of the modern-day Faculty of Science and Engineering of Sorbonne University. As of 2021, its alumni and professors have won 33 Nobel Prizes, six Fields Medals, and one Turing Award.
