Hummel (German: “bumblebee”) was a self-propelled artillery gun based on the Geschützwagen III/IV chassis, armed with a 15 cm howitzer. It was used by the German Wehrmacht during the Second World War from early 1943 until the end of the war.

The full designation 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 being inappropriate for a fighting vehicle.
