Knjaževsko-srpski teatar is the oldest Serbian Theatre based in City of Kragujevac, Serbia, was founded in 1835.

In the autumn of 1834 at the invitation of Grand Duke Milos, Joakim Vujic, best known and highly esteemed person for his theater work, came to Kragujevac with large experience and repertoire. He was very soon appointed Director of the Theater with the task to organize theater work. 

Knjazesko Srbski Teatar - First Serbian Court Theater was placed within the adapted premises of typography and it was a building with the stage, boxes and ground floor. The repertoire of the theater consisted mainly of his plays while the theater ensemble beside Vujic as a leading actor and director consisted of secondary school pupils and adult amateurs. 

First performances were staged in the period of February 2 - 4, 1835 when the so called Sretenje (the Visitation of the Virgin) Assembly sessions were held. These were mostly Vujic's plays performed for the Grand Duke and his family and the representatives of the people i.e. members of Assembly; the music was composed by Jozef Slezinger. For three days they performed four plays Fernando and Jarika, La Perouse, Poor Versifier and Fugitive.

In 1965 this theatre also initiated Meetings of professional Theatres Joakim Vujic of Serbia (in central Serbia) and they were held every year in May in one of ten different towns, until 2003. Since 2004, the Theatre became the regular host of JoakimFest and since October 2006, also of the JoakimInterFest, The International Small Scene Theatre Festival.
