Abstract: Contents of 10 mineral elements in bagged fruits of 53 mango cultivars were determined and analyzed by factor analysis and cluster analysis. The results showed that there were significant differences with wide variability regarding the mineral content in different cultivars，and the average contents of 10 mineral elements followed by the order of K > P > Mg > Ca > Na > Mn > Fe > Zn > Cu > B. The coefficient of variation ranged from 16.79%（P）–52.28%（Mn）. All of the 10 mineral contents distributed normally. Significant correlations were found between Mg and Mn，Zn，Cu，P，K and B，and between P and K. Zn，Cu and K were significantly correlated with each other. K，P，Ca，Mn and B were the characteristic elements of mango. The 53 mango cultivars were divided into 4 clusters；(1) 11 cultivars with high K，P，Mg，Zn and Cu contents，(2) 18 cultivars with high Na and Fe contents，(3) 8 cultivars with low Mg，Zn and K contents，and (4) 16 cultivars with low Ca，B and Mn contents.
