Braunschweigisches Landesmuseum (BLM) is a history museum in Braunschweig, Germany, operated by the state of Lower Saxony.

The museum is scattered on four locations: Vieweghaus, Hinter Ägidien (both in Braunschweig), Kanzlei (Wolfenbüttel) and Bauernhausmuseum (Bortfeld).

The neoclassicist building, the former publishing house of Vieweg Verlag, hosts the main collection, and is located in the city center at the castle square (Burgplatz).

Located in the street Hinter St. Aegidien, this annex exhibits Judaica and was opened to the public in 1746.

This annex focuses on prehistoric and ancient history (500,000 BC until 8th century AD) of the region and was established there in 1959.
