Translation of proper names in children’s literature poses a challenge to many translators who have to consider different aspects when translating them. The first, theoretical part of this paper, will attempt to define children’s literature and children’s literature translation (ChLT) and also mention some implications given by different theorists and researchers. Special focus will also be given to picturebooks, including its definitions, importance in early childhood and some of their specific features such as intertextuality, intermediality and interculturality. The focus will then shift to proper names, their role in literary texts, and different strategies and challenges that the translators use and encounter when translating proper names. Lastly there will be mention of the translator’s freedom and possible restrictions he or she encounters in the translating process. In the second, analytical part of this thesis, the Croatian translations of five different picturebooks: Tabby McTat, The Giant Jumperee, Zog and the Flying Doctors, The Hospital Dog and The Detective Dog by the English author Julia Donaldson are analyzed with special focus on translations of proper names. At the end of this thesis, the findings are compared in order to see which translation strategies are most frequently used and what are the possible reasons behind them.
