The German Panzerwerfer refers to either of two different types of half-tracked multiple rocket launchers employed by Nazi Germany during the Second World War. The two self-propelled artillery vehicles are the 15 cm Panzerwerfer 42 auf Selbstfahrlafette Sd.Kfz.4/1 and 15 cm Panzerwerfer 42 auf Schwerer Wehrmachtsschlepper.

A multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple launchers which are fixed to a single platform, and shoots its rocket ordnance in a fashion similar to a volley gun. Rockets are self-propelled in flight and have different capabilities than conventional artillery shells, such as longer effective range, lower recoil, typically considerably higher payload than a similarly sized gun artillery platform, or even carrying multiple warheads.
