USS L-5 (SS-44) was an L-class submarine of the United States Navy. Her keel was laid down on 14 May 1914 by Lake Torpedo Boat Company in Bridgeport, Connecticut. The L-boats designed by Lake Torpedo Boat (L-5 through L-8) were built to slightly different specifications from the other L-boats, which were designed by Electric Boat, and are sometimes considered a separate L-5 class. L-5 was launched on 1 May 1916 sponsored by Mrs. Rosalind Robinson, and commissioned on 17 February 1918 with Lieutenant J. M. Deem in command.
