Dansk Centralbibliotek for Sydslesvig, Public library in Flensburg, Germany.

The Danish Central Library for South Schleswig stands on Norderstrasse near Flensborghus in Flensburg. Its main building, designed by Holm & Grut and opened in 1959 with an extension from 1987, holds separate adult and children's departments. The library also houses the Schleswig Collection and a study department.

Founded in 1891, this library was established to serve the Danish minority in Schleswig during a period of major cultural shifts. It emerged from the community's need to preserve their language and way of life.

The library is the seat of the South Schleswig Danish Art Association and hosts exhibitions and cultural events, and it takes part in the annual cross-border literature festival litteraturfest.nu. It also houses the secretariat of the Folkeuniversitet and, since 2008, the office of the Nordic Information Office in South Schleswig, one of eight Nordic council-linked offices.

The main library stands on Norderstraße next to Flensborghus, with branches in Schleswig, Husum and Eckernförde and two book buses covering northern Schleswig-Holstein, including regular stops in Kiel. Flensburg, Schleswig and Husum offer wireless network access. Danish courses run in cooperation with Dansk Voksenundervisning i Sydslesvig.

The library's Schleswig Collection (Den Slesvigske Samling) holds over 56,000 volumes on the history of North and South Schleswig, including old Bibles and literature in Danish, German, Low German, South Jutlandic, North Frisian and a few items in Petuh. It was assembled from 1891 and especially after the 1920 Schleswig partition, and is kept apart from the lending stock for researchers.
