Stefano Bartolini (born January 22, 1952) is an Italian political scientist and professor at European University Institute in Florence, Italy. He is the author of many books and publications.^[1][2]

Bartolini is the editor of the Italian political science journal, Italian Political Science Review.

Bartolini's research in political science includes research on electoral changes in Europe during the 1980s, which found that gains and losses at the party level did not translate into large changes at the bloc level. In terms of aggregate scores, the gains of parties within a bloc, whether left-wing or right-wing, were offset by the losses of other parties within the same bloc.^[3]

According to Bartolini, the integration of Europe reverses the centuries-long process of national boundary construction. This provides "exit options" for individuals who had previously been bounded to their nation of birth.^[4]
