USS Tuna/G-2 (SS-27), also known as "Submarine No. 27", was a G-class submarine of the United States Navy (USN). She was the first ship of the USN to be named for the tuna, a large, vigorous, spiny-finned fish highly esteemed for sport and food, though she was renamed G-2 prior to launching.
While the four G-boats were nominally all of a class, they differed enough in significant details that they are sometimes considered to be four unique boats, each in a class by herself.
