The University of Ottawa Students' Union, commonly referred to as the UOSU (French: Syndicat étudiant de l'Université d'Ottawa; SÉUO) is the student organization representing undergraduate students of the University of Ottawa. A student referendum was held in 2019, designating the UOSU as the successor to the Student Federation of the University of Ottawa, after the University of Ottawa terminated its agreement with the SFUO due to allegations of fraud.
