SM UB-46 was a Type UB II submarine or U-boat for the German Imperial Navy (German: Kaiserliche Marine) during World War I. UB-46 operated in the Mediterranean and the Black Seas, and was sunk by a mine in December 1916.
UB-46 was ordered in July 1915 and was laid down at the AG Weser shipyard in Bremen in September. UB-46 was a little more than 121 feet (37 m) in length and displaced between 270 and 305 tonnes (266 and 300 long tons), depending on whether surfaced or submerged. She was equipped to carry a complement of four torpedoes for her two bow torpedo tubes and had an 5-centimeter (2.0 in) deck gun. As part of a group of six submarines selected for Mediterranean service, UB-46 was broken into railcar sized components and shipped to Pola where she was assembled and launched in May 1916, and commissioned in June.
In early December 1916, during the submarine's fifth patrol, UB-46 struck a mine in the Black Sea a short distance from the north entrance to the Bosphorus and sank with all hands. In her six-month career, UB-46 sank four ships of 8,099 gross register tons (GRT).
