A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.

There are over 120 types of brain and spinal cord tumors. In the CNS a tumor may be a malignant secondary tumor having metastasised (spread from a primary site in the body). Secondary tumors are more common in adults.

Treatment and prognosis depend on factors such as the type of tumor, location, and molecular characteristics.
