Swedish Army Museum, Military museum in Östermalm, Stockholm, Sweden.

The institution houses comprehensive collections of military equipment from the 16th century to the present, including uniforms, weaponry, artillery pieces, and transport vehicles. Multiple floors contain thematic galleries arranged chronologically to document the transformation of Swedish warfare across centuries, complemented by interactive exhibits and archival materials.

The museum opened in 1879 as the Artillery Museum at Artillerigården, a site used for military purposes since the mid-17th century and home to the artillery's main depot for nearly 300 years. The present building was designed in 1762 by Carl Johan Cronstedt as a new tyghus, built 1763–1770 to replace a wooden structure. Two storeys were added later, giving its current appearance. Renamed the Army Museum in 1932, it reopened in 1943 and gained the whole building in 1963.

The museum's name changed from Artillery Museum to Army Museum in the early 1930s to match its wider focus. Life-size figures of soldiers from past centuries and scenes of major Swedish battles show the living conditions of soldiers, their families and civilians in war and peace. A room holds trophies and flags taken from armies defeated by Sweden in the 17th and 18th centuries, and a mini-exhibition covers Raoul Wallenberg.

The museum occupies the Artillerigården courtyard block in Östermalm, entered from Riddargatan; the iron fence along that street and all buildings on the site have been state-listed monuments since 1935. The building is owned by the Swedish state and managed by Statens fastighetsverk. Two Second World War air-raid shelters lie beneath the courtyard and are occasionally opened to the public.

The Trophy Chamber displays objects seized by Swedish troops from defeated opponents during numerous conflicts in the 17th and 18th centuries, including rare standards, weapons, and personal items belonging to foreign commanders.
