The Danish minority in Germany is one of the four state- recognised minorities in the Republic. The Danish minority is based in the north of Germany and has its headquarters in Flensburg, however the minority is represented as far as the district of Rendsburg-Eckernförde. The settlement area is also referred to as Sydslesvig/ Südschleswig. The SSF- Sydslesvigsk Forening is the main cultural organisation, although the minority is politically active with its own party, SSW, Südschleswigschen Wählerverband.

The minority is integrated into the school system and has numerous schools where teaching is mainly in Danish. The Danish minority runs a Danish daily newspaper and organises numerous events. Politically, the Danish minority is represented at all levels, and since autumn 2021 it is even represented at federal level with a member of the German Bundestag. Public holidays are celebrated according to Danish tradition and customs. Around 50,000 people declare themselves to be part of the Danish minority in Germany.

The Sinti and Roma have been living in Germany for about 600 years. Depending on where they live, the minority calls itself Sinti or Roma. The minorities living in Western and Central European countries are more commonly called Sinti, whereas those from Eastern and South-Eastern Europe are called Roma. The first records of Sinti and Roma in Germany date back to 1407. In addition to German, the approximately 60,000 Sinti and 10,000 Roma living in Germany speak Romani, which is the minority language.

The Sinti and Roma minority is organised in various associations, with one of the central associations being the Central Council of German Sinti and Roma (Zentralrat der Deutschen Sinti und Roma).

The Frisian ethnic group in Germany lives on the west coast in Schleswig-Holstein and in north-western Lower Saxony. About 60,000 people consider themselves Frisians. The North Frisians (about 10,000 people) live in North Frisia, the East Frisians in north-western Lower Saxony, and the Sater Frisians in Saterland and in the north-western part of the district of Cloppenburg. Depending on their geographical location, the Frisians consider themselves to be North, East or Sater Frisians. Outside Germany, there are also the West Frisians, who are native to the Netherlands.

There are numerous organisations that work to preserve the Frisian language, culture and identity. These are united under the umbrella organisation Frasche Rädj.

The German minority has existed since the referendum and the subsequent demarcation of the border between Germany and Denmark in 1920, which made North Schleswig Danish. The Bonn-Copenhagen Declarations of 1955 laid the foundations for the cultural self-determination of the Danish minority in Germany as well as the German minority in Denmark. The German minority in North Schleswig/Denmark has about 15,000 members.

Their main organization is the Association of German Northern Schleswiger (Bund Deutscher Nordschleswiger, BDN) and thus their representative. It performs political, cultural, social and economic tasks.

The German minority in Denmark maintains its own kindergartens, schools and libraries, carries out church and social work, publishes its own daily newspaper and offers cultural and sporting activities in many associations.
