Christianity is the largest religion in Germany. It was introduced to the area of modern Germany by 300 AD, while parts of that area belonged to the Roman Empire, and later, when Franks and other Germanic tribes converted to Christianity from the fifth century onwards.

In 2020 around 54% of the population were Christians among them 51% members of the two large Christian churches. About half of Christians in Germany are Catholics, mostly Latin Catholics.

Estimations for the percentage of Muslims vary between 3.5% and 6.7%, while much smaller religions include Buddhism, Judaism, Hinduism and Yazidism. The rest of the population is not affiliated with any church, and many are atheist, agnostic, or otherwise irreligious.
