ABSTRACT=Objectives: This study aimed to explore the distribution features and trends of dementia mortality in China from 2011 to 2020 and make a prediction for the next decade.
Methods: Mortality-relevant data were gathered from the Chinese Center for Disease Control and Prevention’s Disease Surveillance Points system. Joinpoint regression was applied to evaluate the trends. 
Results: Crude Mortality Rate (CMR) of AD and other dementias increased from 3.7 per 100,000 to 6.2 per 100,000 in 2011-2020, with an Average Annual Percent Change (AAPC) of 5.3% (95% CI 4.4%–6.3%). Age-Standardized Mortality Rate (ASMR) slightly decreased from 5.0 per 100,000 to 4.1 per 100,000 in 2011-2020, with AAPC of -0.4% (95% CI -2.5%–1.8%). CMR will increase to 9.66 per 100,000 while ASMR will decline to 3.42 per 100,000 in the following decade. 
Conclusion: The upward trend in CMR and a downward trend in ASMR suggested the further development of population aging and dementia mortality in the past and future decades. In China, there were gender, urban-rural, region, and age differences.
