Parliamentary elections were held in Germany on 10 April 1938. They were the final elections to the Reichstag during Nazi rule and took the form of a single-question referendum asking whether voters approved of a single list of Nazi and pro-Nazi guest candidates for the 814-member Reichstag, as well as the recent annexation of Austria. Turnout in the election was officially 99.6% with 99.1% voting 'yes' in Germany and Austria.

Nazi Germany, officially known as the German Reich and later the Greater German Reich, is a term used to describe the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after only 12 years, when the Allies defeated Germany and entered the capital, Berlin, ending World War II in Europe.
