Urban integrated energy system (IES) plays a crucial role in both urban operation and energy transition. Nevertheless, urban IES is extremely vulnerable to extreme events. Therefore, resilience evaluation and enhancement of urban IES will be key towards both climate adaptation and carbon neutrality. Here, we evaluate the IES resilience of 287 cities in China, in terms of robustness, restorability and adaptability, from 2010 to 2019. We find that the median city-level IES resilience in China showed a slight decrease followed by an upward trend. Cities with higher and lower IES resilience values are mainly located in the northeast and southwest China, respectively. We further investigate the IES resilience of five urban agglomerations in China, the results show that the Beijing-Tianjin-Hebei urban agglomeration has the highest level of IES resilience. To reveal the similarity pattern of urban IES resilience, we divided the 287 cities into three groups and predicted the evolutionary trend of their IES resilience under different scenarios. The findings are critical for the resilience enhancement of urban IES and the city as a whole. •This study assessed IES resilience of 287 cities in China from 2010 to 2019.•The median IES resilience showed a slight decrease followed by an upward trend.•Cities with higher IES resilience values are mainly located in the northeast China.•Beijing-Tianjin-Hebei urban agglomeration has the highest level of IES resilience.
