Smart city development plays an important role in achieving urban sustainability. This paper uses mapping of knowledge domain (MKD) analysis to review 965 studies concerning smart city development and urban sustainability (SCDUS). The most influential journals, scholars, articles, keywords, and regions in the SCDUS research field are identified. Research findings also reveal four prevailing topic clusters in the current SCDUS field, namely information technology, energy and environment, urban transportation and mobility, and urban policy and development planning. Potential research frontiers are further proposed. The findings contribute to a better understanding of the development of current SCDUS research.
