The Heuschrecke 10 (English: Grasshopper 10) was a German prototype self-propelled gun and Waffenträger (English: "Weapon carrier") developed by Krupp-Gruson between 1943 and 1944. The official designation of the vehicle was 105 mm leichte Feldhaubitze 18/1 L/28 auf Waffenträger Geschützwagen IVb and was to be built in Magdeburg, Germany. The Heuschrecke featured a removable turret which could be deployed as a pillbox or towed behind the vehicle as an artillery piece.

Krupp produced only three prototypes from 1942–1943. The Heuschrecke initially made use of a shortened Panzerkampfwagen IV (Panzer IV) chassis, but it was later switched to the Geschützwagen IV chassis, developed for the Hummel self-propelled gun. Mass production of the Heuschrecke 10 was scheduled to start in February 1945, but never occurred.

The distinguishing feature of the Heuschrecke was its removable turret. A lifting gantry attached to the chassis could remove the turret for use on concrete fortifications or the ground. Although the howitzer could equally be fired from the chassis, the vehicle was designed to carry the artillery piece to a firing emplacement for removal before usage. The turretless vehicle could be used as an ammunition carrier or recovery vehicle. The prototype turret was armed with the 105 mm leFH 18/1 L/28. The production models, however, were to have the 105 mm leFH 43 L/28.
