SM U-30 or U-XXX was a U-27 class U-boat or submarine of the Austro-Hungarian Navy. U-30, built by the Hungarian firm of Ganz Danubius at Fiume, was launched in December 1916 and commissioned in February 1917.

U-30 had a single hull and was just over 121 feet (37 m) in length. She displaced nearly 265 metric tons (261 long tons) when surfaced and over 300 metric tons (295 long tons) when submerged. Her two diesel engines moved her at up to 9 knots (17 km/h) on the surface, while her twin electric motors propelled her at up to 7.5 knots (13.9 km/h) while underwater. She was armed with two bow torpedo tubes and could carry a load of up to four torpedoes. She was also equipped with a 75 mm (3.0 in) deck gun and a machine gun.

U-30 sank no ships during her brief service career. She departed from Cattaro on 31 March 1917 and was never heard from again. She may have succumbed to a mine in the Otranto Barrage but her fate remains a mystery.
