The Association of Serbian Youth (Serbian Cyrillic: Дружина младежи српске) was the first student organisation in Serbia, founded in 1847 by the students of the Lyceum of the Principality of Serbia.
Among the founders were Jevrem Grujić and Petar Protić Sokoljanin.
This organisation was banned and disestablished in 1851 because of their criticism of the Defenders of the Constitution.
