Hummel (German: "bumblebee") was a German self-propelled gun used by the Wehrmacht during World War II. Based on the Geschützwagen III/IV chassis and armed with the 15 cm sFH 18/1 L/30 howitzer, it saw action from early 1943 until the end of the war. Its ordnance inventory designation was Sd.Kfz. 165.
The full name was Panzerfeldhaubitze 18M auf Geschützwagen III/IV (Sf) Hummel, Sd.Kfz. 165. On February 27, 1944, Hitler ordered the name Hummel to be dropped as it was deemed inappropriate for a fighting vehicle.
