The minimum age depends on the jurisdiction. For India , the minimum age for appointment as a Governor is 35 years.

If you meant the United States

There is no single nationwide minimum age for a state governor in the U.S.; it varies by state. Many states require 30 years old , while some require 25, 21, 18, or 31 , and a few have no formal age requirement.

If you want, I can also tell you the minimum age for a specific country or state.
