The main purpose of this research is to reveal the identity to be constructed with the illustrations in the life science textbooks in terms of identity types. Case study, one of the qualitative research designs, was used in the research. The data sources of the research consist of the 1st, 2nd and 3rd grade life science textbooks taught in Turkey in 2021-2022. The research used 'content analysis' to provide a detailed description based on the purpose of the study. The illustrations in the life science textbook of the 1st, 2nd and 3rd grade are coded separately with regard to the types of identity in the literature. Categories and themes were the result of the combination of the codes. In life science textbooks, only illustrations that could have a connection with identity construction have been analysed. As a result of the research, it has been determined that the illustrations for the collective identity are prominently included in the life science textbooks. In the theme of collective identity, there are illustrations emphasizing national, social and religious identity. For digital identity and universal identity topics, there are a limited number of illustrations.
