Presl.) is the representative species of subtropical evergreen broadleaved forests in eastern Asia and an important raw material for essential oil production worldwide. Although MYBs have been comprehensively characterized and their functions have been partially resolved in many plants, it has not been explored in <i>C. camphora</i>. In this study, 121 <i>CcMYBs</i> were identified on 12 chromosomes in the whole genome of <i>C. camphora</i> and found that <i>CcMYBs</i> were mainly expanded by segmental duplication. They were divided into 28 subgroups based on phylogenetic analysis and gene structural characteristics. In the promoter regions, numerous <i>cis</i>-acting elements were related to biological processes.
