Jeremiahaus, Former church community centre in Altstadt-Süd, Cologne, Germany.

Jeremiahaus is a former Protestant community centre with an integrated church hall at Mozartstraße 15 in the Komponistenviertel on the western edge of Cologne's city centre. From the street it looks like an ordinary 1960s brick apartment block; only a small bell tower, a display case and a cross hinted at its function. The church hall itself stood on the garden side, invisible from the street, and the building was consecrated in 1964.

The Jeremiahaus opened on 6 December 1964, the second Sunday of Advent, on the site of a war-damaged parish house at Mozartstraße 15 that was demolished in January 1962. The congregation built a combined church hall, community rooms and flats for the pastor, a deaconess and the sexton on the small plot; a planned kindergarten was dropped for lack of space. Financial pressure led to its deconsecration on 26 November 2006, the first church closure in the history of the Evangelical parish of Cologne.

The house is named after the prophet Jeremiah. From 1972 the Finnish Evangelical Lutheran congregation of Cologne, founded that year and counting over 1,000 members in the early 2000s, held its services here because it had no church of its own. The building also housed a children's playgroup started by parents in 1991, which became the childcare initiative "Die Mozartkugeln e. V.", still active in 2022.

The Jeremiahaus stood at Mozartstraße 15 in the Komponistenviertel, on the western edge of Cologne's inner city. From the street it looked like a 1960s brick apartment block; only a small bell tower, a display case and a cross marked it out. The church hall itself lay on the garden side, invisible from the pavement.

The upper floor had a hall for 60 people and a terrace on the church roof, from which visitors could see the neighbouring synagogue on Roonstraße. The entrance walkway's supports were originally dark, later painted bright blue. The bell tower formed the street end of that canopy.
