Chengdu is located at the center of Sichuan Province in southwestern China, and its primary demographic group is the Han population. The aim of this study was to contribute data detailing 17 Y-short tandem repeat (Y-STR) loci from 3291 Chengdu Han male samples analyzed with the AmpFLSTR® Yfiler® PCR Amplification Kit. We observed 2228 different haplotypes, and haplotype diversity (HD) was 0.9992. Gene diversity (GD) values for the 17 Y-STR loci of the Chengdu Han population ranged from 0.4156 to 0.9529. Haplotype match probability (HMC) was 0.0011. Compared with 13 reference populations of six provinces surrounding Chengdu, we observed that the Chengdu Han population was significantly different from each of these populations.
