USS Grampus/A-3 (SS-4), also known as "Submarine Torpedo Boat No. 4", was a Plunger-class submarine, and the fourth ship of the United States Navy to be named for a member of the dolphin family, Grampus griseus. She was stationed on the West Coast, assisting in the relief efforts after the San Francisco earthquake of 1906, and was later transported to the Philippines, serving as harbor defense during WWI.
