The majority of studies on second/foreign language teacher identity have explored the face-to-face environment compared to the technology-assisted language learning (TALL) environment. The paucity of research despite the significance of teacher identity served as the rationale to conduct a systematic review. Scopus and Web of Science indexed journal articles on language teacher identity that met the predetermined exclusion-inclusion criteria were systematically reviewed. Forty-four articles published between 2010 and 2020 were reviewed to convey the reported affordances and challenges of distance learning for language teacher identity. Pedagogically, the findings inform pre-service and practicing teachers who seek a better understanding of teacher identity in TALL in terms of affordances and challenges. Theoretically, the findings shed light on the future research trend and inform researchers about the most frequently reported challenges that need to be addressed concerning L2 teacher identity.
