Howard Hughes Holdings Inc., formerly the Howard Hughes Corporation, is a real estate development and management company based in The Woodlands, Texas. It was formed in 2010 as a spin-off from General Growth Properties (GGP). Most of its holdings are focused on several master-planned communities. It took its name from the original Howard Hughes Corporation, which had developed the planned community of Summerlin, Nevada, and later became a subsidiary of GGP.

Summa Corporation was a holding company for the business interests of Howard Hughes after he sold the tool division of Hughes Tool Company in 1972. Its holdings included casino hotels, aviation businesses, and television channels. After Hughes's death in 1976, most of the company's assets were sold off, and it focused on developing the master-planned community of Summerlin, Nevada. Summa was renamed as The Howard Hughes Corporation in 1994. It was acquired by The Rouse Company in 1996.
