Abstract：Heat shock protein 20（HSP20），an essential protein in the process of plant growth and development，HSP20 plays crucial roles inplants under stress．Based on genomic data of melon（Cucumis melo L.），whole genome identification of the HSP20 gene family was carried out using bioinformatics，and their physical and chemical properties，colinearity，gene structure，evolutionary relationship and cis-elements were analyzed．The results showed that 42 HSP20s were identified in the melon genome data，molecular weight ranging from 8 390.40 to 57 350.14 Da，the intron number of 0 to 12，were unevenly distributed on 12 chromosomes．In colinear analysis，there were 32 genes in melon existing collinearity relation with cucumber，watermelon and pumpkin．Phylogenetic tree reveals 9 pairs of orthologous genes and 8 pairs of paralogous genes of CmHSP20．Multiple cis-elements associated with hormonal response，stress response，photoresponse，and plant development were identified in the promoter of the CmHSP20s gene．
