Christianity:
Lörrach initially belonged to the diocese of Konstanz and was under the archdiocese of Breisgau.
In 1529, after the Reformation had been introduced there, the parsonage of Lörrach was occupied from Basel.
The reformation in the city was introduced in 1556.
After that, Lörrach was for many centuries a predominantly Protestant city.
In Rötteln, an archdiocese had existed since the beginning of the 15th century, which at the end of the 17th century, shifted to Lörrach.
The Protestant pastor of Lörrach was from 1682 an intendant, too.
The Stadtkirche is the main church of Lörrach (first mentioned in the 12th century).
In addition, Lörrach has a few parishes: Johannespfarrei (founded in the 20th century), Pauluspfarrei for the northern city (founded in 1906), Matthäuspfarrei for the eastern city, Inzlingen (founded in 1949), Markuspfarrei (founded in 1956), Salzertgemeinde (founded in 1969), and Friedensgemeinde for the district of Homburg (founded in 1974).

The borough of Stetten was controlled by Austria until 1803.
Therefore, Stetten has a Catholic tradition, although the reformation had been introduced years before.
Because of a contract with Austria, Stetten again became Catholic.
At first, the parish of Stetten also served the resident Catholics of Lörrach.
They held their church services in the new church, the Fridolinskirche (1822).
The original church of Stettens was founded in the 13th century.
Between 1864 and 1867 in Lörrach, its own parish church (St. Bonifatius) was built, at which a curacy was created that was raised to the status of a parsonage in 1882.
A second Catholic church (St. Peter) was built in 1964.
In Brombach, they had already built in 1900 a church (St. Josephskirche), which has been a parsonage since 1911.
All Catholic parishes of Lörrach today form together with the neighbouring parishes of St. Peter and Paul in Inzlingen a group pastoral ministry within the deanery of Wiesental belonging to the archbishopric Freiburg.

Today, a slight predominance of the Lutheran denomination exists.
In the borough of Stetten exists a relative Catholic majority.

Beside the two large churches, some  parishes belong to free churches.
For example, the Freie evangelische Gemeinde or FeG Lörrach (English: Free Evangelical community).
