Science, technology, engineering and mathematics (STEM) has become a frequently discussed topic in education in recent years. This study aims to categorize research findings related to Educational Robotics through Integrated STEM Learning towards 21st century skills in 2019-2024. In its review, this study used PRISMA systematic review. Paper searches were conducted on Scopus, ScienceDirect, and DOAJ databases on December 2023-January 2024. A total of 30 articles to review. The review in this study made it possible to categorize the Implementation of Integrated STEM in the form of Educational Robotics towards the development of 21st century skills in two categories. The first category was based on the improvement of students' abilities, the learning and teaching process, and the relationship with 21st century skills. The second category was based on the evaluation of STEM integrated with Educational Robotics to support 21st century skills. The results from the first category had a strong influence in improving students' abilities, the learning and teaching process, and the relationship with 21st century skills. From the second, it was determined that there is a need for the development of methods in learning educational robotics and it is important to support 21st century skills.
