Gymnasium Vukovar (Croatian: Gimnazija Vukovar)) (Serbian: Gimnazija Vukovar/Гимназија Вуковар) is a secondary school situated in Vukovar, Croatia. Gymnasium Vukovar carries the educational programs of general secondary school, science and language direction. Classes are taught in Croatian or Serbian language. In the school year 2007/2008, 384 students were enrolled. Of these, there were 248 female and 136 male students.
The school opened in 1891 in the Kod zvijezde with 44 male pupils, and the first principal was Joseph Vitanović. In 1894, it moved to premises built for that purpose which had been constructed between spring and autumn of that year at a cost of 35,500 forints. In 1895, female pupils were also enrolled, and partial state funding began, culminating in full state funding in 1912, when the school had about 240 pupils. In 1999, the pupils studying the two languages were taught in separate buildings. Some have seen that fact the implementation of segregation policies on what specifically insisted Croatian nationalist groups. However, it is important to emphasize that parents themselves can choose in which language the department enrolls a child. It is also important to point out that this case can not be considered discriminatory by the Convention against Discrimination in Education. In fact, Article 2, paragraph B, explicitly stated that this type of situation shall not be deemed to constitute discrimination.
