The current trend in urban planning has been evolved for developing the cities smart. Smart city concept directs urban development in to a strategic path to achieve sustainability in urban development. The understanding made up on the concept of smart city within any region would be fruitful to review in this nature. Similarly, the various stakeholders who would influence and contribute on smart city development projects are profound to identify in order to make the project success. As previous researches denoted, a timely and effective consultation of relevant stakeholders is of paramount importance for the success of any project. In line of thinking, this research was aimed to conduct a stakeholder analysis through a comprehensive literature review. Thirty one (31) key literature projects were obtained from recognised research databases and were critically reviewed to identify the internal and external project stakeholders of smart city development projects. As the key findings, the concept of smart city was first recognised. Secondly, academia and research institutions, local and regional administrations, financial suppliers/investors, energy suppliers, ICT sector representatives, citizens, government, property developers, non-profit organisations, planners, policy makers, experts and scientists, political institutions and media were identified as key internal and external stakeholders of a smart city development project. The key research findings were presented through a conceptual framework. The developed framework could be utilised as a basis to analyse the different influences and contributions of stakeholders of smart city development projects in any context.
