SM U-10 or U-X was the lead boat of the U-10 class of submarines for 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-1.

SM UB-1 was constructed in Germany and shipped by rail to Pola where she was assembled and launched in January 1915. She was commissioned into the German Imperial Navy later that same month and sank an Italian torpedo boat in June. The boat was handed over to Austria-Hungary and commissioned as SM U-10 in July. In May 1917, U-10 was fired upon by a British submarine, but both of the torpedoes that were launched missed. In July 1918, U-10 hit a mine and was beached with heavy damage. She was towed to Trieste for repairs which remained unfinished at the war's end. U-10 was handed over to Italy as a war reparation and scrapped in 1920.
