A pineoblastoma is a rare malignant brain tumor which arises from the cells of the pineal gland which sits near the center of the head and brain. They are a form of primitive or undifferentiated tumor which displays pathology which is very abnormal, quickly growing and invasive.

While other types of tumors are more common in the region of the pineal gland, such as a pineal germinoma, a pineoblastoma is one of the more malignant tumors found in this area. These high-grade tumors are related to and on a spectrum with more benign variants which are called pineocytoma, pinealocytoma or pinealoma (all different names for the same benign tumor).
