ABSTRACT Climate change poses a serious threat to global species distributions and has significantly altered the distribution patterns of invasive species. Coreopsis spp. are widely distributed invasive plants with strong adaptability and reproductive capacity, whose invasion has become a major ecological concern in China. Using three climate change scenarios (SSP‐126, SSP‐245, SSP‐585), combined with the Maximum Entropy (MaxEnt) model and Geographic Information System (ArcGIS), this study delineated the potential distribution areas and distribution centroids of invasive Coreopsis plants in China. The results indicated that temperature (especially isothermality BIO3 and mean temperature of the warmest quarter BIO10) and moisture are the primary climatic factors influencing the distribution of Coreopsis spp., while human activity (HA) also plays a key role in shaping their distribution. Coreopsis drummondii exhibited the largest suitable habitat area (4.138 × 10 6 km 2 ), whereas Coreopsis verticillata had the smallest (9.53 × 10 5 km 2 ). Under current climatic conditions, the six Coreopsis species are mainly distributed in southern China. In future climate scenarios, their distributions are projected to shift northward and toward plateau regions. Moreover, high niche and range overlap was observed among Coreopsis grandiflora , Coreopsis lanceolata , and Coreopsis tinctoria , suggesting potential intensified interspecific competition. This study systematically reveals the invasion potential and spatial dynamics of Coreopsis spp. under climate change, providing a scientific basis for early warning, regional management, and ecological control. It also offers perspectives for future research on the interaction mechanisms between invasive and native species.
