St. Joseph, Parish church and architectural monument in Siemensstadt, Germany.

St. Joseph is a dark red brick church with a projecting entrance portal framed by two rough grey stone jambs and a flat dark canopy. Above the grey metal doors, a rectangular relief panel shows six scenes from the life of Saint Joseph. Inside, eight pointed concrete arches spring from the floor and meet along a central ridge, forming a white vaulted ceiling.

Catholics in Siemensstadt first gathered in a school drawing hall and later in a Siemens administration courtyard; a makeshift church with bell tower and apse was consecrated on 2 November 1918. The permanent brick church, designed by Siemens building director Hans Hertlein on land donated by the company, was begun in 1934 after the 1932–33 economic crisis and consecrated on 17 November 1935. Damaged in the Second World War, it remained in use for Mass. The parish was raised to a parish in 1939 and merged into Heilige Familie – Spandau-Havelland on 1 January 2023.

The parish grew from a 1915 church-building association; services were first held in a school drawing room and a Siemens administration hall. The brick relief above the entrance shows scenes from the life of Saint Joseph, the church's patron. Since 2023 the parish belongs to Heilige Familie – Spandau-Havelland.

The church stands on Goebelstraße, with the parish hall entrance at Natalissteig 2 and the two-storey rectory at Quellweg 43. The main doors are reached by grey stone steps, and the interior is entered from the west front. The complex lies in the Siedlung Heimat, built 1930–1935, in eastern Siemensstadt.

The church was designed by Hans Hertlein, the Siemens company's chief architect, and the land was donated by the Siemens works. Its square tower with a flat pyramid roof and rows of sound openings echoes the industrial buildings of Siemensstadt rather than traditional church towers.
