The National Smart Cities Mission, launched by the Government of India in 2015, aims to develop sustainable and intelligent urban environments across the country. This study examines the implementation of the mission by the Union Ministry of Urban Development in collaboration with state governments, focusing on budget allocation, engagement in different cities, sustainability measures, and future prospects. It also explores the challenges faced, technological integrations, and funding models. The research uses a mixed-methods approach, combining primary and secondary data, to analyze the mission's objectives, governance, and public perception. Key aspects include community engagement, resource efficiency, innovative solutions, and technology integration through IoT, smart grids, and digital infrastructure. The mission has improved urban services, enhanced public safety, and promoted economic growth, but faces challenges such as funding, bureaucratic procedures, and data security. Despite these challenges, the mission has significantly enhanced urban infrastructure, governance, and quality of life, serving as a model for other countries dealing with rapid urbanization.The National Smart Cities Mission, launched by the Government of India in 2015, aims to develop sustainable and intelligent urban environments across the country.
