The Day of German Unity (German: Tag der Deutschen Einheit) is the national day of Germany, celebrated on 3 October as a public holiday. It commemorates the anniversary of German reunification in 1990, when the goal of a united Germany that originated in the middle of the 19th century, was fulfilled again. Therefore, the name addresses neither the re-union nor the union, but the unity of Germany. The Day of German Unity on 3 October has been the German national holiday since 1990, when the reunification was formally completed.

An alternative choice to commemorate the reunification could have been the day the Berlin Wall came down: 9 November 1989, which coincided with the anniversary of the proclamation of the German Republic in 1918, and the defeat of Hitler's first coup in 1923. However, 9 November was also the anniversary of the first large-scale Nazi-led pogroms against Jews in 1938 (Kristallnacht), so the day was considered inappropriate as a national holiday. (See November 9 in German history.) Therefore, 3 October 1990, the day of the formal reunification, was chosen instead and replaced the "Day of German Unity" on 17 June, the national holiday of the Federal Republic of Germany from 1954.

Before 1871, in the area where the single state of Germany now exists, different kingdoms and principalities existed. After the unification of Germany, and the Founding of the Empire 1871, there was still no common national holiday. The Sedantag was, however, celebrated every year on 2 September, recalling the decisive victory in the Franco-Prussian War on 2 September 1870.
