Sergej Trifunović is a Serbian actor, comedian, singer, politician and citizen activist.

In late 2018, a series of largely peaceful protests over the rise of political violence and against the authoritarian rule of Serbian President Aleksandar Vučić and his governing Serbian Progressive Party (SNS) began to take place in the Serbian capital of Belgrade, soon spreading to cities across the country, as well as in cities with the Serbian diaspora. The demonstrations have lasted more than a year and they become the most prolonged mass anti-government demonstrations in Serbia since the time of the Bulldozer Revolution and some of the longest-running in Europe.
