The aim of this study is to examine graduate studies on the use of origami in mathematics. Document analysis method was used to examine the graduate studies included in the study. While collecting the data, the thesis classification form developed by Ceylan and Bozkurt (2023) was used. The data were collected from the Council of Higher Education Thesis Documentation system. Criterion sampling was used in the study. Twenty postgraduate studies examined with certain criteria were reached. The data were analyzed using content analysis. Percentage and frequency calculations were made in the study. When the results of the study were examined, it was seen that the most common theme in the studies was the effect of origami on certain variables, the year was 2012, the type of research was master’s thesis, and the university where the postgraduate studies were conducted was Ondokuz Mayis University. Methodologically, it is seen that quantitative methods, experimental designs, random sampling, secondary school student sample group, sample size between 1-50, test and personal information form data collection tools, descriptive statistics and parametric test data analysis were mostly used.
