In the context of smart cities, where sustainability, efficiency, and digital integration are crucial, modular construction has become a game-changing method of urban development. This study does a bibliometric analysis to identify research trends and collaborations in modular construction within smart city environments. The study finds important issues, significant writers, and developing research trends by methodically analysing the Scopus database. Retrieving publications over the previous ten years, emphasising journal articles, conference proceedings, and book chapters, was part of the research technique. The VOSviewer analysis showed that publication trends for modular construction research in smart cities have fluctuated. The results indicate two main thematic clusters demonstrating how modular construction might improve urban resilience and adaptation by integrating digital technology, automation, and sustainability. In order to lay the groundwork for future multidisciplinary research and policy development, this study offers a thorough bibliometric review of modular construction research in smart cities. To support scalable and sustainable smart city solutions, the report suggests increased collaborative research efforts, real-world case studies on implementing modular constructions, and the integration of digital twin technologies and open-access data. The research fills in current knowledge gaps with this bibliometric evaluation, providing insights into how modular construction might enhance housing accessibility, maximise urban development, and encourage ecologically conscious city design in the age of smart cities.
