Alfred Howe Terry (November 10, 1827 – December 16, 1890) was a Union general in the American Civil War and the military commander of the Dakota Territory from 1866 to 1869, and again from 1872 to 1886.

After attending Yale Law School in 1848, Terry became a lawyer and was appointed clerk of the Superior Court of New Haven County.

Troops under Terry's direct command were engaged at a skirmish at Grimball's Landing and later succeeded in capturing Fort Wagner in September 1863, but the following year the entire X Corps was sent north to Benjamin Butler's Army of the James in Virginia.

Terry had gained the confidence of General Ulysses S. Grant and was now in command of the ground forces in a second expedition against the fort.

On January 13, 1865, Terry sent a division of United States Colored Troops to hold off Confederate forces under Braxton Bragg to the north of Fort Fisher.

He helped to negotiate the Treaty of Fort Laramie (1868), which ended Red Cloud's campaign against American troops in the region.

Terry was the commander of the U.S. Army column marching westward into the Montana Territory during what is now popularly known as the Centennial Campaign of 1876–77.

His aide-de-camp, Robert Patterson Hughes, who was also his brother-in-law, investigated Custer's activities before and during the battle and authored a critical report.

Terry is interpreted by Philippe Noiret in the 1974 Franco-Italian satirical Marco Ferreri movie Don't Touch the White Woman!, a farcical, counter-cultural, highly politicized and surreal re-enactment of the run up to the 1876 Battle of the Little Bighorn.
