SM U-38 was a German Type U 31 U-boat which operated in the Mediterranean Sea during World War I. It ended up being the third most successful U-boat participating in the war, sinking 134 merchant ships sunk for a total of 287,811 GRT.

Its longest serving captain was Kptlt. Max Valentiner, who was awarded the Pour le Mérite while in command of U-38. Valentiner was in command of U-38 in November and December 1915 when she sank the passenger liners Ancona and Persia; both were controversial since the ships were sunk by torpedoes without warning, in defiance of the then-current Prize rules, which stated that merchant vessels carrying passengers be given an opportunity to evacuate their passengers before being sunk.

In 1917 Valentiner was succeeded as commander of U-38 by Kptlt. Wilhelm Canaris, who decades later became an Admiral and head of the Abwehr (German Military Intelligence), in 1935–1944.
