William Henry (Judge) Moore (1848 – January 11, 1923) was an attorney and financier. He organized and promoted or sat as a director for several steel companies that were merged with among others the Carnegie Steel Company to create United States Steel. He and his brother James Hobart Moore helped create the Diamond Match Company, National Biscuit Company, First National Bank, the Delaware, Lackawanna and Western Railroad, the American Can Company, the Lehigh Valley Railroad, the Chicago, Rock Island and Pacific Railroad, the Continental Fire Insurance Company, the Western Union Telegraph Company, the American Cotton Oil Company, and Bankers Trust. Moore was an avid and expert horsemen.

He was born in 1848. Moore's father, Nathaniel Ford Moore, was a prominent banker and merchant in Utica, New York. His mother, Rachel Arvilla Beckwith, was a daughter of George Beckwith, also a banker, a mid-18th century graduate of Yale College, and member of the original Yale Corporation.

After a few years at Amherst College, Moore sought adventure in the American West, where he became known to Sitting Bull. Moore returned to the American Midwest on Sitting Bull's advice. Moore then joined the law firm of Edward Alonzo Small, his future father-in-law, and invited his brother James Hobart to join him in Chicago. After Small's death, Hobart partnered with his brother, and married the sister of his sister-in-law
