The Church of St. Joseph is a Roman Catholic church in the Swiss city of Basel. It is located in the Matthäus-Quartier in the immediate vicinity of the Evangelical Reformed St. Matthew's Church and is consecrated to Joseph of the Old Testament.
The church was designed in the historicist neo-baroque style; Baroque is unique for the traditionally reformed city of Basel. The Josephskirche was built between 1900 and 1902 by the St. Gallen architect August Hardegger as a parish church for the rapidly growing Catholic population in the workers' quarters in Kleinbasel. With its originally 1,400 seats, it is the largest Catholic church in Basel. Hardegger had also planned a variant with a dome, but the version with a wide three-aisled hall was implemented.
The glass paintings are by Friedrich Berbig. The choir altar by the painter August Wanner was created in 1926 and shows two murals of Joseph in Egypt. The altarpieces are by Rudolf Blätter and Fritz Kunz (1868–1947). The organ was made in 1904 by the organ builder Theodor Kuhn in Männedorf.
In 1988 the interior of the church was renovated; the renovation of the facade took place in 1997. In 1996 the building was included in the city's list of monuments after consultation with the owner and on the basis of a municipal law of December 1994.
