The Final Solution or the Final Solution to the Jewish Question was a Nazi plan for the genocide of individuals they defined as Jews during World War II. The "Final Solution to the Jewish question" was the official code name for the murder of all Jews within reach, which was not restricted to the European continent. This policy of deliberate and systematic genocide starting across German-occupied Europe was formulated in procedural and geopolitical terms by Nazi leadership in January 1942 at the Wannsee Conference held near Berlin, and culminated in the Holocaust, which saw the murder of 90% of Polish Jews, and two-thirds of the Jewish population of Europe.

The Jewish question, also referred to as the Jewish problem, was a wide-ranging debate in 19th- and 20th-century Europe that pertained to the appropriate status and treatment of Jews. The debate, which was similar to other "national questions", dealt with the civil, legal, national, and political status of Jews as a minority within society, particularly in Europe during the 18th, 19th, and 20th centuries.
