The U-10 class was a class of five U-boats —U-10, U-11, U-15, U-16, and U-17— of the Austro-Hungarian Navy during World War I. The class was similar to the German Type UB I submarine of the German Imperial Navy (). The boats were small coastal submarines that displaced surfaced and submerged. The first two boats delivered to Austria-Hungary had previously been commissioned in February 1915 by the Kaiserliche Marine, while the remaining three were commissioned by the Austro-Hungarian marine in April 1915.
