Ludwigsburg is a city in Baden-Württemberg, Germany, about 12 kilometres (7.5 mi) north of Stuttgart city centre, near the river Neckar. It is the largest and primary city of the Ludwigsburg urban district with about 87,000 inhabitants. It is situated within the administrative region (Regierungsbezirk) of Stuttgart.

The middle of Neckarland, where Ludwigsburg lies, was settled in the stone and bronze ages. Numerous archaeological sites from the Hallstatt period remain in the city and surrounding area.

Towards the end of the 1st century, the area was occupied by the Romans. They pushed the Limes further to the east around 150 and controlled the region until 260, when the Alamanni occupied the Neckarland. Evidence of the Alamanni settlement can be found in grave sites in the city today.

The origins of Ludwigsburg date from the beginning of the 18th century (1718–1723) when the largest baroque castle in Germany, Ludwigsburg Palace was built by Duke Eberhard Ludwig von Württemberg. Originally, the Duke planned to just build one country home (albeit a palace), which he began building in 1704. However, the examples of other princes fostered a desire to project his absolutist power by establishing a city. To the baroque palace, he added a hunting lodge and country seat, called Schloss Favorit (1713–1728), and the Seeschloss (castle on the lake) Monrepos (1764–1768).
