Weilbach is a market municipality in the Miltenberg district in the Regierungsbezirk of Lower Franconia (Unterfranken) in Bavaria, Germany.

The municipality is divided into the centres of Weilbach, Weckbach, Gönz, Reuenthal, Ohrenbach, Wiesenthal and Sansenhof.

The knight Cunrat von Wilenbach was witness to a land deal of the House of Dürn, which he served.

In 1977, under municipal reform, Weckbach with its outlying centres of Gönz, Ohrnbach, Wiesenthal and Sansenhof was amalgamated with Weilbach.

The municipality's arms might be described thus: Per mantle argent a fountain with three spouts, dexter, affronty and sinister, before which a trough azure, in chief dexter gules a wheel spoked of six of the first, in chief sinister a cogwheel spoked of four and toothed of twelve of the first.

From the Gotthardsruine, half of which is within Amorbach’s town limits, there is a panoramic view over the Odenwald and on into the Spessart (range).

It was then that the Gaugraf (regional count) Ruthard von Frankenberg supposedly called the missionaries Saint Pirmin and Amor to the “Gotthard”.

On the northwest route out of Weilbach stands the mill with its Renaissance gable converted by Mainz court master builder Ambrosius Brosamer in 1585.

At the beginning of the 19th century, the factory der Eisenhammer (“The Iron Hammer”), now belonging to The Linde Group, was founded.

From 1967 to 1984, as Chairman of the Bavarian Municipal Assembly (Bayerischer Gemeindetag), he took on responsibility for the Miltenberg district chapter.

In 1985 he became an honorary citizen and in 1991 he was awarded the Kommunale Verdienstmedaille (a Bavarian medal for municipal service) in silver.
