SM UB-44 was a Type UB II submarine or U-boat for the German Imperial Navy (German: Kaiserliche Marine) during World War I. UB-44 operated in the Mediterranean and disappeared in August 1916.
UB-44 was ordered in July 1915 and was laid down at the AG Weser shipyard in Bremen in September. UB-44 was about 37 metres (121 ft 5 in) 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-44 was broken into railcar sized components and shipped to Pola where she was assembled and launched in April 1916 and commissioned in May.
In two patrols in her three-month career, UB-44 sank one ship of 3,409 gross register tons (GRT). In early August 1916, UB-44 departed from Cattaro for Hersingstand and never arrived. Her fate is officially unknown, but she may have been sunk by a torpedo boat near the island of Paxoi on 8 August.
