The Faculty of Social Sciences (FSS) (Czech: Fakulta sociálních věd Univerzity Karlovy) is one of the newest faculties of Charles University. The Faculty was founded in 1990, shortly after the Velvet Revolution. It soon became a regional centre of teaching and research in area studies, economics, international relations, journalism, media studies, sociology and political science. The Faculty offers bachelor's, master's, and doctoral degree programs in social sciences. While the languages of instruction are Czech and English, students can choose from classes in a wide range of other languages, including French, German, Russian and Spanish.

The Faculty enrolls around 5,000 full-time students, including 1,000 international students.
