The Turmberg (German: "Tower Hill") is a hill (elevation: 256 m) located in Durlach, a suburb of Karlsruhe in Germany.

It is home to a castle ruin.

The Turmberg can be reached by the Turmbergbahn, a funicular railway.

The original railway used water to counterbalance the rail cars, but now it is run on electricity.
