The Archäologisches Museum Hamburg (Hamburg Archaeological Museum; formerly the Helms-Museum) is an archaeological museum in the Harburg borough of Hamburg, Germany. It houses the archaeological finds of the city of Hamburg and the neighbouring counties to the south of the city. It focuses on northern German prehistory and early history as well as the history of the former city of Harburg. The museum is also home to the cultural heritage landmarks commission of the city of Hamburg and the adjacent district of Harburg in Lower-Saxony and thus supervises all archaeological undertakings in the region.
The museum has two major exhibition spaces. The future City Museum of Harburg, temporary exhibitions, the library, offices and small storage facilities are located in the main building, which is shared with the Harburger Theater at Museumsplatz 2. The permanent archaeological exhibition and education facilities are located nearby, at Harburger Rathausplatz 5. In addition, the Museum maintains as external branches the exhibition area of the 12th-century Bischofsturm (Bishop's Tower) in Hamburg's old town, the Fischbeker Heide archaeological trail at Neugraben-Fischbek and the 8th-century hillfort of Hollenstedt.
