The ability to think creatively is an essential skill in the 21st century. This research aims to analyze students' creative thinking abilities by implementing Project-Based Learning Integrated with Science, Technology, Engineering, and Mathematics (STEM-PjBL) on motion dynamics material. The research method is descriptive qualitative, with data obtained through observation, interviews, and student worksheet documents. The research results show that two indicators are in a suitable category, namely fluency and authenticity, while the other two indicators, flexibility and elaboration, are in the poor category. Recommendations that can be given based on the results of this research include the need to integrate the STEM-PjBL method more deeply into physics learning to improve all indicators of creative thinking abilities, especially flexibility, and elaboration. This research emphasizes the importance of learning that prioritizes students as the center of learning to develop various essential creative thinking skills.
