The aim of this study is to determine analogies that are used in Turkish secondary school mathematics textbooks. According to this aim, 7 textbooks are analysed: 3 of them are published by the commission of Ministry of Education and 4 of them are published by private publishing companies. The document analysis method is used in the study. Analogies are classified with respect to their analogical relationship, presentational format, abstraction, position of analogue with respect to target and level of wealth. Classified analogies were examined separately within the relevant textbooks and added to the findings by specifying the total number of analogies. Then the data were analyzed and reported. As a result of the research, it was found that analogies are dominantly structural, verbal-pictorial, preliminary and simple
