Background Sudden cardiac death (SCD) represents a public health concern globally. Given the lack of large‐scale comprehensive studies on the epidemiologic features and spatial clustering of SCD in general populations, particularly in the context of cardiovascular and cerebrovascular events in China, this study aims to enrich the evidence base by analyzing its current situation in Shandong Province. Methods County‐level data from Shandong Province (2020–2021) were used to investigate whether the incidence of SCD varied by age and sex, between urban and rural areas, among different regions, and explored whether a trend toward concentration in its temporal and spatial distribution was evident. Results Shandong Province reported a total of 30 458 cases of SCD from 2020 to 2021, peaking in January to April. Most cases occurred in the older population, aged ≥65 years, comprising 78.70% of the total mortality (23 972/30 458). The male/female ratio for the average annual crude and age‐standardized mortality rates was 1:0.98 and 1:0.75, respectively, whereas the urban/rural ratio was 1:1.61 and 1:1.40, respectively. Global spatial autocorrelation analysis revealed significant clustering trends of age‐standardized mortality rates for both years (Moran I of 0.15 and 0.13, respectively, both P
