This study investigates the benefits of formulating research teams within the context of Vietnam, focusing particularly on researchers specializing in Teaching English to Speakers of Other Languages (TESOL), English as a Foreign Language (EFL) teaching and learning, French as a Foreign Language (FFL) teaching and learning, and Language and Linguistics. Through semi-structured interviews with 12 researchers of varied experiences, Grounded Theory and thematic analysis were utilized to unravel key benefits. The findings reveal that team-based  research offers advantages including enhanced knowledge sharing, skills diversification, improved decision-making, expanded research scope, access to greater resources, increased accountability, opportunities for leadership and teamwork skills, and more. The study underlines the immense potential of collaborative research in the Vietnamese context. The conclusions drawn emphasize the necessity for institutions to encourage and facilitate team-based research practices, offering important insights for policy formulation. While providing nuanced understanding of the Vietnamese research context, the study acknowledges limitations, including its narrow disciplinary focus and reliance on participant interviews. Recommendations for future research include exploring challenges within research teams, conducting cross-cultural and interdisciplinary studies, examining the impact of technology and leadership styles on team dynamics, and exploring the role of institutional support.
