Stefan Seidler

Stefan Seidler (born 18 December 1979) is a Danish-German politician of the South Schleswig Voters' Association (SSW), the party representing the interests of the Danish and Frisian minority populations in Germany. Thus, the SSW is not subject to the general requirement of passing a 5% popular vote share threshold to gain proportional seats in state parliament and the Bundestag, just the much lower threshold to win a seat, about 0.16% for the Bundestag with 630 seats. The SSW has been represented in the Landtag of Schleswig-Holstein since 1958, and last contested a federal election in the 1961 West German election.

Seidler was elected to the 20th Bundestag from Schleswig-Holstein in the 2021 German federal election. His election represented the first time the SSW won a seat since Hermann Clausenin 1949. He was elected again in 2025.
