The late "Sopranos" star also left millions to his wife and relatives.
The New York Post reports that a will dated Dec. 19 was filed Tuesday in Manhattan Surrogate's Court.
Gandolfini's son, Michael, is to get the largest chunk through a trust set aside for him until he turns 21.
He'll split his father's Italian property with his half-sister, 8-month-old Liliana, when she turns 25.
The newspaper says the remainder of Gandolfini's estate will be split among his wife, sisters and daughter.
He left $200,000 each to his personal assistant and secretary.
The will is the first and primary filing of his estate; more documents are expected to be filed.
Gandolfini died June 19.
