Of the many uses of social media, educationists advocate its use for teaching the English language. The traditional method of learning the English language is associated with inattention among learners. The adoption of social media in teaching the English language can create a fun, stress-free, and pleasant environment that is able to cultivate a positive attitude among the learners. Hence, this study carried out a systematic review to assess the use of social media for English learning in the Southeast Asia context. The study systematically searched the peer-reviewed literature using the SCOPUS database and identified 46 articles. After thorough reading, 21 articles met the inclusion criteria. Articles that were excluded from the analysis were conducted outside Southeast Asia, do not focus on Southeast Asia’s English learning, and do not engage with social media usage. The findings suggest that the use of social media for English learning was associated with improving communication skills, enhancing collaborative learning, encouraging self-directed learning, enhancing writing skill and learning experience.
