The invention provides a hot stamping die and a process for a high-strength martensite steel plate, belonging to the technical field of hot stamping. The die consists of an upper die and a lower die. In the invention, an indirect hot stamping process comprising a cold pre-stamping step and a secondary hot stamping step is adopted, or an indirect hot stamping process comprising a hot pre-stamping step and a secondary hot stamping step is adopted, or a direct hot stamping process only comprising a hot stamping step is adopted. By the process disclosed by the invention, the problem that defects such as crack and the like often occur when a plate is subjected to cold stamping pre-forming in the indirect hot stamping forming process is solved, and the yield of pre-formed workingpieces is improved. By the adoption of the invention, the pre-forming and hot forming two-step process can be completed only by one set of die; and direct and indirect hot stamping functions can be achieved by changing die modules, the use efficiency of the dies is improved, and the hot stamping process and die costs are reduced.
