Burg- und Schlossmuseum Jägersburg, Regional history museum in Jägersburg, Homburg, Germany.

The Burg- und Schlossmuseum Jägersburg is a local heritage museum founded in 1984 by the Heimat- und Verkehrsverein Jägersburg and housed in the Gustavsburg, an old Staufer castle. Its collection centres on the Dukes of Zweibrücken, to whose domain Jägersburg belonged from the early 15th century, with replicas of the Greinberg portraits and paintings by Zweibrücken artists such as Ziesenis and Mannlich.

The museum preserves artifacts from Celtic burial mounds that are up to 2600 years old, as well as objects from the Gallo-Roman period. These items reveal early settlement and cultural change in the region over many centuries.

The core of the collection concerns the Dukes of Zweibrücken, to whose domain Jägersburg belonged from the early 15th century. It holds replicas of the Greinberg collection, with nearly all the dukes' portraits, and works by Zweibrücken painters such as Ziesenis and Mannlich, including replicas of Mannlich's self-portrait and his portrait of Duke Christian IV.

The museum has limited availability, opening only on Sundays and public holidays during warmer months. Visitors should check current opening times beforehand, as availability is seasonal.

The archive holds around 30,000 charters and deeds, many sealed by notable issuers, alongside a large collection of seals from feudal lords tied to Jägersburg, including seals of the kings of Sweden who at times held authority over the place.
