Abstract With the rapid growth of research in English‐medium instruction (EMI) in higher education, much research has been conducted through qualitative and quantitative approaches. Yet, little attention was paid to the use of mixed‐methods research (MMR) in this field. Therefore, this systematic review aims to examine previous literature that adopted MMR in EMI research, specifically evaluating the methodology across three aspects: epistemological orientation and purpose, MMR question formulation, and MMR design. Among 136 studies identified, substantial methodological gaps were found across all three aspects. First, only seven studies explicitly stated an epistemological orientation whereas 27 studies provided explicit purpose terminology. Second, only six studies explicitly presented an integrative MMR question, while 112 studies provided qualitative and/or quantitative research questions, and 18 studies lacked explicit research questions. Finally, MMR design characteristics were rarely described: (1) nearly half of the studies did not specify a design, (2) no study used specific sampling procedure terminology, and (3) questionnaires and interviews were the most frequently used instruments. Based on these methodological gaps, this study offers recommendations for strengthening future EMI studies that employ a mixed‐methods approach.
