Herman August Metz (October 19, 1867 – May 17, 1934) was an American businessman and politician who served one term as a U.S. Representative from New York from 1913 to 1915.

[2] Metz was married twice, first, from 1891 to 1915 to Laura A. Traudt, from whom he was divorced, and second, from 1916 onward, to the former Mrs. Alice M. Norman (nee Van Ronk).

Metz attended private and public schools and rose to prominence as a manufacturer and importer of dyestuffs, chemicals, and pharmaceuticals.

[1] From school he entered the employ of P. Schulze-Berge as an office boy in 1881, remaining with the firm through various consolidations and changes and advancing through the ranks to become its vice-president and general manager by 1893, and its majority stockholder and president in 1899.

[2] He also became president of H. A. Metz Laboratories, Inc., Ettrick Mills, Textileather Company, and New York and Hanseatic Corporation, a member of numerous chemical and industrial societies, and a director with a number of banks.

As a German-American businessman with extensive ties to German manufacturing interests, he favored American neutrality during the early years of the First World War.

[1] After his death Metz was honored together with U.S. founding father Alexander Hamilton in the naming of Hamilton-Metz Field, a 2.1-acre (0.0085 km2) park in the Wingate neighborhood of Brooklyn.
