To explore the relationship between community support in tourist destinations and residents' psychological well-being in the post-COVID-19 pandemic period, this study adopts the questionnaire survey method and draws the following conclusions by constructing a structural equation model: (1) perceived community support is very helpful for the psychological well-being of residents, (2) psychological resilience significantly mediates the relationship between perceived community support and residents' psychological well-being, (3) the resident-tourist interaction mediates the relationship between perceived community support and residents' psychological well-being, and (4) the resident-tourist interaction and psychological resilience play an ordered chain-mediating role between perceived community support and residents' psychological well-being. These findings not only fill the gap in tourism research regarding destination-based community support studies but also provide a theoretical basis for maintaining residents' psychological well-being in a given destination in the context of the COVID-19 pandemic. To a certain extent, improving residents' well-being is helpful for promoting the healthy and sustainable development of tourism activities and realizing a "win-win" situation in which tourist destinations develop economically while promoting their residents' living standards.
