Durlach is a district in Karlsruhe, Germany, with a population of roughly 30,000.

The district is further divided into Alt-Durlach, Dornwald-Untermühl, Hanggebiet, Bergwald, Aue, Lohn-Lissen and Killisfeld.

Durlach was bestowed by emperor Frederick II on the margrave Hermann V of Zähringen as an allodial possession.

It was chosen by the margrave Charles II in 1565 as residence of the rulers of Baden-Durlach, and retained this distinction though it was almost totally destroyed by the French in 1689.

Margrave Charles III William decided that he needed more space which led to the foundation of Karlsruhe in 1715, which three years later became the new capital until the state was merged into the grand-duchy of Baden.

In 1846, it was the seat of a congress of the Liberal Party of the Baden Parliament. In 1849 during the Baden Revolution, it was the scene of an encounter between the Prussians and the insurgents.

In 1938, Durlach was incorporated into Karlsruhe, which had was now bigger and connected by a canal and an avenue of poplars with it, on the left bank of the Pfinz, at the foot of the Turmberg.

During the Second World War, 329 people were killed in Durlach.^{[citation needed]}
