This study aims to produce a systematic literature review on trends in English language education research in Indonesia over the last three years (2019-2021) from an ontological perspective. The Systematic Literature Review (SLR) writing process was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) framework. The analysis of data resulted in identifying the categories of ontology, namely the categories of teaching, learning, assessing, development of teaching documents like syllabus, learning materials, learning media and instructional model. From these categories of ontology, these studies have been identified and discussed. From the result, it is shown that from the 152 included studies, some areas of English language education tend to have great interest in researching trends of teaching, learning and learning media development. The study also identifies the number of study topics categorized as teaching has increased significantly in the last three years, while the number of research topics categorized as evaluation has decreased. Furthermore, there are two key sources which influence these trends. Firstly, it is due to the COVID-19 pandemic. Second, it is because of the dependency on convenience sampling. Based on the results and interpretations, the authors suggest future research to inform the current situation of research development in English language education.
