Robert R. Hitt, American politician, 13th United States Assistant Secretary of State (born 1834)

Robert Roberts Hitt was an American diplomat and Republican politician from Illinois. He served briefly as assistant secretary of state in the short-lived administration of James A. Garfield but resigned alongside Secretary of State James G. Blaine after Garfield's assassination in 1881. He returned to Washington to represent Northwestern Illinois in the United States House of Representatives from 1882 to his death. After 1885, he was the senior Republican on the House Committee on Foreign Affairs, which he chaired from 1889 to 1891 and 1895 until his death in 1906.

Assistant Secretary of State (A/S) is a title used for many executive positions in the United States Department of State, ranking below the under secretaries. A set of six assistant secretaries reporting to the under secretary for political affairs manage diplomatic missions within their designated geographic regions, plus one assistant secretary dealing with international organizations and one equivalent as the coordinator/ambassador at large for counterterrorism. Assistant secretaries usually manage individual bureaus of the Department of State. When the manager of a bureau or another agency holds a title other than assistant secretary, such as "director", it can be said to be of "assistant secretary equivalent rank". Assistant secretaries typically have a set of deputies, referred to as deputy assistant secretaries (DAS).
