Elbert Henry Gary (October 8, 1846 – August 15, 1927) was an American lawyer, county judge and business executive. He was a founder of U.S. Steel in 1901 alongside J. P. Morgan, William H. Moore, Henry Clay Frick and Charles M. Schwab. The city of Gary, Indiana, a steel town, was named for him when it was founded in 1906.

Gary, West Virginia was also named after him. When trust busting President Theodore Roosevelt said that Gary was head of the steel trust, Gary considered it a compliment. The two men communicated in a nonconfrontational way, unlike Roosevelt's communications with leaders of other trusts.
