This paper reports the results of a review of 33 journal articles chosen from 87 empirical studies on learner identity in Chinese as a foreign/second language (CFL/CSL) education, published during the years 2005-2019. By analyzing the co-occurrence of keywords in these Social Science Citation Index (SSCI) journal articles, this review identifies the theoretical perspectives and topical trends of CFL/CSL education research on learner identity. The review shows that while such post-structuralist theories and notions as capital, identity and investment model have continued to play a predominant role in CFL/CSL identity research, interdisciplinary perspectives seem to also demonstrate their theoretical value and interpretive power. Furthermore, the review found that researchers explored a wide array of topical issues in relation to learner identity involved in the complex linguistic and social ecology of Chinese language learning. The review concludes with suggestions for future projects to consider that expand the thematic and theoretical scope by exploring intersections between different social categories and learner identities in societal contexts.
