USS Thrasher/G-4 (SS-26), also known as "Submarine No. 26", was a G-class submarine of the United States Navy (USN). Thrasher was the first ship of the USN to be named for the thresher shark, a shark with a long dorsal tail fin, though she was renamed G-4 prior to being launched.

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.
