The 7th Connecticut Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War.

It mustered out on July 20, 1865, and discharged at New Haven, Connecticut, on August 11, 1865.

[1][2] In October and November 1863, the regiment's status changed.

It was equipped as a "boat infantry" for the specific purpose of leading an amphibious night assault on Fort Sumter, South Carolina.

Although the 7th trained at Folly Island, South Carolina, the project was ultimately ended because it was deemed impractical.
