German submarine U-9 was a Type IIB U-boat of Nazi Germany's Kriegsmarine. Her keel was laid down on 8 February 1935, by Germaniawerft in Kiel as yard number 543. She was launched on 30 July 1935 and commissioned on 21 August, with Korvettenkapitän Hans-Günther Looff in command.

U-9 conducted 19 patrols under a series of commanders, including U-boat ace Wolfgang Lüth, sinking eight ships totalling 17,221 gross register tons (GRT) and damaging another displacing 412 tons. This included the French Sirène class coastal submarine Doris.

She was sunk by Soviet bombs on 20 August 1944. Her wreck was later raised by the Soviets, repaired and recommissioned as TS-16 but was broken up in December 1946 because of her poor performance.
