Spokeswoman Alla Plotkin says Moore's doctors recommended the elective procedure after monitoring the tumour for some time. Plotkin did not say when the surgery would take place.
It would remove a meningioma, a slow-growing tumour in the membranes that cover the brain. Meningiomas usually occur in older adults and are mostly benign.
The 74-year-old Moore gained stardom as a modern suburban housewife on the 1960s comedy "The Dick Van Dyke Show," then went on to headline her own successful series as a single woman pursuing a career.
Moore's plan to have the surgery was first reported on People magazine's website.
