The 31st Motorized Infantry Division is a military formation of the People's Liberation Army (PLA) of the People's Republic of China.

The division's equipment and training are geared towards operating in a variety of environments and conducting offensive and defensive operations as part of larger combined arms formations. The specific composition and equipment of the 31st Motorized Infantry Division are subject to change as the PLA continues to modernize.
