SM UB-49 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the German Imperial Navy on 28 June 1917 as SM UB-49.

UB-49 served mainly in the Mediterranean. In the Austro-Hungarian Navy she was listed as SM U-80. In eight wartime patrols she sank 40 ships totaling 81,486 gross register tons (GRT) and one escort. After the Armistice with Germany UB-49 returned to Kiel via Norway. Handed over to the United Kingdom on 16 January 1919, she was broken up in Swansea in 1922.

UB-49 was ordered by the German Imperial Navy on 20 May 1916. She was built by Blohm & Voss, Hamburg and following just under a year of construction, launched at Hamburg on 6 January 1917. UB-49 was commissioned later that same year under the command of Kapitänleutnant (Kptlt.) Hans-Joachim von Mellenthin. Like all Type UB III submarines, UB-49 carried 10 torpedoes and was armed with an 8.8 centimetres (3.5 in) deck gun. UB-49 could carry a crew of up to 34 men and had a cruising range of 9,040 nautical miles (16,740 km; 10,400 mi). UB-49 had a displacement of 516 t (508 long tons) while surfaced and 651 t (641 long tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 8 knots (15 km/h; 9.2 mph) when submerged.
