SM U-11 or U-XI was a U-10-class submarine in the Austro-Hungarian Navy (German: Kaiserliche und Königliche Kriegsmarine or K.u.K. Kriegsmarine) during World War I. She was originally a German Type UB I submarine commissioned into the German Imperial Navy (German: Kaiserliche Marine) as SM UB-15.

SM UB-15 was constructed in Germany and shipped by rail to Pola, where she was assembled and launched. She was commissioned into the German Imperial Navy in April and sank an Italian submarine in June. The boat was handed over to Austria-Hungary and commissioned as SM U-11 on 14 June. In early 1916, U-11 fired on a British submarine, but missed. After the end of the war, U-11 was handed over to Italy as a war reparation and scrapped at Pola by 1920.
