Herborn (German pronunciation: [ˈhɛʁˌbɔʁn] ⓘ) is a historic town on the Dill in the Lahn-Dill district of Hesse in Germany.

Scenic attractions include its half-timbered houses; Herborn is located on the German Timber-Frame Road.

(in each case on 31 December) Herborn had its first documentary mention in 1048, and was granted the privilege of a city in 1251 by the Counts of Nassau.

In 1584 the Herborn Academy, a Reformed (Calvinistic) institution, was founded by John VI of Nassau-Dillenburg, younger brother of William the Silent and namesake of today's Gymnasium Johanneum.

This work has had a decisive effect in shaping church life among followers of the Reformed movement in Germany, the Netherlands, Switzerland and the United States.

After the Congress of Vienna Herborn was in a border area next to Prussia, and its economy suffered due to import tariffs.

In the Second World War, Herborn was mostly spared by the bombers, but its Jewish community was obliterated in 1942, and many of the patients of the psychiatric clinic were deported and murdered.

After losing control because of faulty brakes, a tanker truck carrying about 34 000 L of fuel ran into a house containing an ice cream parlour and a pizzeria.
