The Warsaw Ghetto was the largest of the ghettos in Nazi-occupied Europe, located in the territory of General Government in occupied Poland during World War II.

The Warsaw Ghetto was established by the German Governor-General Hans Frank on October 16, 1940. Frank ordered Jews in Warsaw and its suburbs rounded up and herded into the Ghetto. At this time, the population in the Ghetto was estimated to be 400,000 people, about 30% of the population of Warsaw; however, the size of the Ghetto was about 2.4% of the size of Warsaw. The ghetto was split into two areas, the "small ghetto", generally inhabited by richer Jews and the "large ghetto", where conditions were more difficult; the two ghettos were linked by a single footbridge. The Nazis then closed the Warsaw Ghetto from the outside world on November 16, 1940, by building a wall, topped with barbed wire, and deploying armed guards.

The Warsaw Ghetto Uprising was the Jewish resistance that arose within the Warsaw Ghetto in German occupied Poland during World War II, and which opposed Nazi Germany's effort to transport the remaining ghetto population to Treblinka extermination camp.

The insurgency was launched against the Germans on January 18, 1943. The most significant portion of the rebellion took place from April 19 until May 16, 1943, and ended when the poorly armed and supplied resistance was crushed by the German troops under the direct command of Jürgen Stroop. It was the largest single revolt by the Jews during the Holocaust.
