Background and Importance: Chondrosarcoma is a rare malignant cartilage forming tumor, usually arising from long bones and rarely observed in the cranium. In the cranium, it commonly arises from the skull base with the skull vault being a highly unusual site.  Case Presentation: We present the case of a ۳۰-year female presenting with complaints of headache for ۶ months. The patient was found to have large chondrosarcoma in the right frontoparietal region, which is an extremely rare location. The final diagnosis was based on histological examination, suggestive of well-differentiated chondrosarcoma [the World Health Organization (WHO); grade I].  Conclusion: Cranial vault chondrosarcoma is an uncommon histological diagnosis with surgery as the primary treatment option; however, adjuvant radiotherapy plays a definitive role, especially in aggressive or incomplete removed cases.
