Henry Parkman Jr. (April 26, 1894 – May 27, 1958) was an American politician who served in various offices in Massachusetts and the United States federal government.

After the war, Parkman went in the transportation business, delivering goods from New England manufacturers to the Pacific Coast via the Panama Canal.

[5] In 1928 he challenged long-time party leader Charles Hiller Innes in a high-profile contest to be the 11th Congressional District delegate to the Republican National Convention.

Parkman ran a campaign against bossism and stated that "Mr. Innes does not represent the party, but only a small number who have made a business out of politics".

[8] Parkman was expected to receive the endorsement of the Good Government Association, however the group backed Frederick Mansfield instead.

[10] Parkman received 12% of the vote, which placed him behind Mansfield (28%), Nichols (27%), and William J. Foley (25%) and ahead of Joseph F. O'Connell (4%) and Michael H. Sullivan (4%).

[15] Following his defeat, Parkman was offered a position on the legal staff of United States Under Secretary of War Robert P.

[21] In April 1946, Parkman returned to Germany at the request of Lt. Gen. Lucius D. Clay to serve a one-year as chief of the Civil Administration Branch in the American zone.

[24] Later that year he was appointed by the Civil Service Commission to serve on a panel for federal workers whose loyalty to the United States was questioned.

In 1953, he was nominated for the position of Massachusetts Director of Civil Defense, however he withdrew in order to become assistant to United States High Commissioner for Germany James Bryant Conant.
