The 7th New Hampshire Infantry Regiment was an infantry regiment of the Union Army during the American Civil War. It was raised in the state of New Hampshire, serving from December 13, 1861, to July 17, 1865. Because it was in the same brigade as the 7th Connecticut Infantry Regiment, both regiments together were often jointly called the 77th New England.
