Kosta Hakman (; 22 May 1899 – 9 December 1961) was a Yugoslav and Bosnia and Herzegovina painter. Early life Hakman was born in 1899 in Bosanska Krupa, the third child of local judge Mihailo Hakman, who descended from Polish Catholic immigrants, and Darinka Đurić, a teacher of Bosnian Serb descent from Sarajevo. He had three brothers, Mihailo, Stefan and Nikola and two sisters, Jelena and Zora. He was baptized in the Serbian Orthodox faith. He finished elementary school in Tuzla. In 1908, he started attending the Grammar School in Tuzla, thought to be one of the best schools in Bosnia at the time, and also known for its liberal ideas nurtured by both professors and students.

Training Due to the lucky circumstance that he happened to be in Sarajevo in the autumn of 1917, he had the opportunity to visit the exhibition in the great hall of the Country Government where the work of all the most well-known painters from Bosnia and Herzegovina at the beginning of the 20th century was displayed. The encounter with these works of art crucially influenced his decision to become a painter, which he dreamed of in Tuzla where the influence of his teachers infected him with the beauty of artistic creation. Therefore, immediately upon his graduation, he sent the Managerial Board of the publishing house in Sarajevo, Prosveta, a letter asking for a grant in the amount of 500 crowns to further his education.
