Abstract Compound flood‐heatwave extremes (CFHWs) have threatened the sustainable development of human society and ecosystems. However, disproportionate risks in regions with different economic under a warming climate not been quantified. This study carries out global investigation on future CFHWs three scenarios based 11 models from Coupled Model Intercomparison Project Phase 6 (CMIP6). Results reveal 7.5‐fold increase annual CFHW days by 2100 intermediate greenhouse‐gas‐emission scenario SSP2‐4.5 compared to that 1980. Under SSP2‐4.5, population exposure low‐income countries late (2071–2090) will be about 9‐fold higher than high‐income baseline period (1995–2014). Moreover, poor groups living less $6.85/day nearly 28.1‐fold. Eastern Africa South Asia are identified as particularly high‐risk regions, where large populations poverty face rapidly increasing CFHWs. These findings indicate inequality become more pronounced if continues without immediate effective measures. Our also underscores urgent need for mitigation adaptation strategies against CFHWs, especially vast regions.
