The Student Union of the University of Turku (TYY, in Finnish Turun yliopiston ylioppilaskunta) is a body to which, under public law, all University of Turku bachelor's and master's degree students belong.
TYY was founded in 1922 and it joined the National Union of University Students in Finland (SYL) in 1927.
TYY is amongst the first student unions that has made their fixed-term secretariat positions permanent in spring 2008 due to the dispute brought up in labour court about fixed-term working relationships that the Union of Students in Finnish Universities of Applies Sciences (SAMOK) lost in February 2088.
[1] The Student Union of the University of Turku enforces the lobbying of education, social policy and international affairs at the university, city and national levels.
TYY owns, among others, the majority of the student cafeterias and cafés in the campus area run by Unica Oy.
