Württembergische Landesbibliothek, State library in Stuttgart, Germany.

The Württembergische Landesbibliothek is a research library in Stuttgart holding millions of books and documents across its collections. The facility includes reading rooms, archive spaces, and specialized sections dedicated to different subject areas.

The library was founded in 1765 and later moved from Ludwigsburg to Stuttgart, becoming part of the city's cultural infrastructure. In the 20th century it suffered war losses but recovered through systematic reconstruction efforts.

The Bible collection holds over 20,000 printed Bibles, among them a Gutenberg Bible bought in 1978 and the only complete copy of William Tyndale's English Bible. The manuscripts section keeps more than 15,000 manuscripts, including the Zimmern Chronicle acquired with 700 Donaueschingen manuscripts. The Hölderlin Archive holds manuscripts and first editions of Friedrich Hölderlin and edits the International Hölderlin Bibliography.

The library operates with flexible hours on weekdays and Saturdays, allowing visitors time to research and read. The spaces are accessible and equipped with search systems to make navigation and use straightforward.

The air raid of 12–13 December 1944 destroyed most of the building and over 400,000 volumes, including all literature published after 1930 and most of the former Court Library. Only the administrative building holding the catalogues survived. The most valuable items had been moved outside Stuttgart beforehand. Horst Linde's new building opened on the old site on 3 August 1970.
