Techically, that would be the U.S. Navy's first submarine, USS S-1 (SS-105) , built by John Phillip Holland. Though the first submarine that was used in combat, David Bushnell's Turtle (Revolutionary War), the U.S. wasn't in fact a country at that time.
The Confederate submarine H.L. Hunley was also not technically an American submarine, effectively being used by the Confederate Army (manned by Confederate sailors), but it was never a commissioned vessel in any navy.
The first submarine was called the Turtle or American Turtle. It was a one man submarine and powered like a bicycle. It was designed to attach explosive devices to the hulls of British ships. All such attempts failed.
