Hines Interests Limited Partnership is an American privately held company that invests in and develops real estate.

The company initially began as a side-business to an engineering partnership after Gerald D. Hines moved to Houston for work in 1948.

[11] In the 1990s, Hines had developed its own standards for indoor air quality, which influenced rules later established by the United States Environmental Protection Agency.

[13] A 2005 report by the Lipsey Company,[14] recognized Hines as one of the largest real estate firms in the world, with operations throughout the U.S. and across the globe.

[10] Many of the firm's buildings were designed by well-known architects, including I. M. Pei, Cesar Pelli, Frank Gehry, and Robert A.M.

At the end of 2016, Hines completed the construction of T3, a 7-story, 224,000 square-foot office building consisting mainly of heavy timber, harvested from managed forests to maximize sustainability.

[24] The company continued on, forming a joint venture with the National Pension Service of Korea to focus on build-to-core properties in the U.S. in December 2020.

[27] In July 2024, Pinellas County commissioners approved a deal with the Tampa Bay Rays and Hines, who sought to develop 65 acres of land within the Historic Gas Plant District, and to build Gas Plant Stadium, a new $1.3 billion baseball stadium replacing Tropicana Field as the Rays home arena.

The deal includes a $50 million commitment from the Rays and Hines toward at least 5,000 residential units (including affordable and workforce housing), small business assistance, job creation and educational programs, plus $10 million for a new museum for the Dr. Carter G. Woodson African American Museum.
