Although many scholars have conducted studies on language learning strategies (LLS) around the world, little scholarly work reports on the LLS used by multilingual English learners. Moreover, most of those prior studies have been carried out employing exclusively quantitative methods. In response to these gaps, the present study adopts a qualitative approach to explore the LLS use of Indonesian multilingual English learners at a university in Indonesia. We gathered in-depth information from 11 participants who spoke at least three foreign languages through semi-structured interviews and demographic questionnaires. Findings indicated that the LLS used by the participants were using fun learning resources, communicating with others in English, employing digital technology, evaluating and seeking feedback, and practicing independently. Interestingly, learning other languages helps them further their understanding of English. The findings of this study also suggest that language learners can adapt to the way multilingual students learn English. In addition, the article discusses the implications of the results for educators and educational institutions, and provides recommendations for the next researchers.
