The German destroyer Z1 Leberecht Maass was the lead ship of her class of four destroyers built for the German Navy during the mid-1930s. Completed in 1937, two years before the start of World War II, the ship served as a flagship and spent most of her time training, although she did participate in the occupation of Memel in early 1939.

The Type 1934 destroyers, also known as the Z1 class or Leberecht Maass class after the lead ship, were a group of four destroyers built for the German Navy during the mid-1930s, shortly before the beginning of World War II. The ships were engaged in training for most of the period between their commissioning and the outbreak of war, although they did participate in the occupation of Memel in Lithuania, in early 1939. Z3 Max Schultz collided with and sank a German torpedo boat shortly before the war began on 1 September 1939. All four ships were named after German officers who had been killed in World War I.
