This study conducts a bibliometric review of Industry 4.0 (I4.0) research in the Indian manufacturing sector from 2019 to August 2025 to synthesize fragmented evidence and identify thematic trends. Using Scopus data and analysis through Biblioshiny (R), sixty empirical papers were examined. The results show a 36.6% annual growth rate and strong international collaboration, reflecting the field’s rapid development. Six key thematic clusters emerged: strategic modeling, sustainability, quality and performance, enabling technologies, empirical validation, and methodological approaches. The findings indicate that I4.0 adoption in India is primarily driven by leadership commitment, policy support, and technological readiness, while constrained by skill shortages, financial limitations, and infrastructural gaps. The study enhances understanding of how digital transformation contributes to sustainable industrial growth and provides practical insights for managers and policymakers to advance India’s Industry 4.0 agenda.
