USS R-13 (SS-90), also known as "Submarine No. 90", was an R-1-class coastal and harbor defense submarines of the United States Navy commissioned after the end of World War I.

Due to space constraints, the boats built at the Fore River Shipbuilding Company yard, were laid down much later than the boats built at the Union Iron Works and the Lake Torpedo Boat Company yards. Because of this, none were commissioned before the end of WWI.
