Anders' Army was the informal yet common name of the Polish Armed Forces in the East in the 1941–42 period, in recognition of its commander Władysław Anders. The army was created in the Soviet Union but, in March 1942, based on an understanding between the British, Polish, and Soviets, it was evacuated from the Soviet Union and made its way through Iran to Palestine. There it passed under British command and provided the bulk of the units and troops of the Polish II Corps, which fought in the Italian Campaign. Anders' Army is notable for having been primarily composed of liberated POWs and for Wojtek, a bear who had honorary membership.

The Polish Armed Forces in the West refers to the Polish military formations formed to fight alongside the Western Allies against Nazi Germany and its allies during World War II. Polish forces were also raised within Soviet territories; these were the Polish Armed Forces in the East.
