Thomas Hamlin Hubbard (December 20, 1838 – May 19, 1915) was a Union Army colonel from Maine during the Civil War who was awarded the honorary grade of brevet brigadier general, United States Volunteers, for meritorious service.

[6] He had a hand in the construction of the famous Red River Dam, which was built to raise the water level so that Federal gunboats which had run aground could be floated out of danger, and his services as a whole were so conspicuous and so valuable that on June 2, 1864 he was made colonel of his regiment.

[6] On January 13, 1866, President Andrew Johnson nominated Hubbard to the honorary grade of brevet brigadier general, to rank from March 13, 1865.

He gave the law up in 1894 in order to devote more time to his numerous business interests, including management of the estate of railroad magnate Mark Hopkins.

Bowdoin College was a favorite object of his benefactions, and among the donations that remain are the splendid Hubbard Hall (designed by Henry Vaughan) and the fine grand stand which displays the motto, "Fair Play, and May the Best Man Win."

A more enduring monument is Cape Thomas Hubbard, which, from the wind-swept coast of Grant Land, faces the North Pole across reaches of grinding pack-ice, over which Robert E. Peary, another Bowdoin man, carried the Stars and Stripes in 1909.
