Rockefeller Group International, Inc. is an American private company based in New York City, primarily involved in real estate operations in the United States and it is a subsidiary of Mitsubishi Group.

By the early 1970s, it had added a total of four International Style towers to Rockefeller Center, more than doubling the size of the original complex.

Today, Rockefeller Group maintains an ownership/management position in the 7,700,000 square feet (720,000 m2) of office space that makes up Rockefeller Center's western corridor (the newer buildings located west of Sixth Avenue).

The eastern and original part of the Center is now owned by Tishman Speyer (who also serves as manager) and the Lester Crown family of Chicago, Illinois.
