ABSTRACT This scientometric analysis examines 688 research publications on English medium instruction (EMI) from 2003 to 2022, sourced from the Web of Science database. This investigation employs growth trend analysis, discipline analysis, co-authorship analysis, document co-citation cluster analysis, and document co-citation burstness analysis to unravel the overall state, cooperation network, and foundational and emerging trends of the research themes. Three growth phases are identified: limited interest (2003–2013), fluctuating development (2014–2017), and rapid growth (2018–2022). The fields of education and linguistics dominate the disciplinary landscape. Six research clusters are identified from the analysis, encompassing the following topics: (1) English learning affordance, (2) policy, realities, and challenges, (3) language support, (4) stakeholders’ perspectives, (5) academic success, and (6) global Englishes. Citation bursts indicate emerging trends, including global English integration, multilingualism advocacy, and innovative language assessment. Geographically, international research collaboration is encouraged, while temporally, the maturation and evolution of each EMI research specialty (cluster) is observed. In conclusion, future research on EMI should adopt a multidisciplinary approach, provide nuanced language support, conduct continuous policy analysis, and comprehensively investigate academic and stakeholder success.
