Wetter (Hessen) is a small town in Hesse, Germany. The rather unusual designation Wetter (Hessen-Nassau) stems from a time when the town belonged to the Prussian province of the same name, and nowadays is only used by the railway – even today, the railway station in town bears this name.

Wetter lies in the Marburg-Biedenkopf district on the western edge of the Burgwald, a low range of hills, in the Wetschaft valley and neighbouring places about 14 km north of Marburg.

To the north, Wetter borders on the town of Rosenthal in Waldeck-Frankenberg district, to the east on the town of Rauschenberg and the community of Cölbe, to the south on the community of Lahntal, to the southwest on the community of Dautphetal, and to the southwest on the town of Biedenkopf and the community of Münchhausen am Christenberg, all in the Marburg-Biedenkopf district.

North to south through the town's municipal area runs the Federal Highway (Bundesstraße) B 252 from eastern Westphalia by way of Korbach and Frankenberg and on to Göttingen (in the community of Lahntal). To divert heavy traffic away from places in the Wetschaft valley, a bypass road is planned.

The Burgwaldbahn railway line connects the town with Marburg and Frankenberg. The Kurhessenbahn which runs the line means to reopen the extension between Frankenberg and Korbach.

Wetter was already being mentioned in documents in the 8th and 9th centuries; it was mentioned in one such document under the same name that it still has today in 1108, and the "Weistum of Wetter" was already displaying its town rights even as early as 1239.

As of municipal elections held on 26 March 2006, the seats on Wetter Town Council are apportioned thus:

CDU	12 seats
SPD	12 seats
FDP	3 seats
Greens	3 seats
Left Party	1 seat

Wetter's civic coat of arms might be described thus: In Or on a three-knolled hill vert a fleur-de-lis twig vert with three blossoms argent flanked by two inescutcheons, dexter in azure the Hessian Lion rampant gules and argent sinister; sinister in gules the wheel of Mainz argent.

The two inescutcheons (smaller shields within the main one) hark back to the time when the Hessian Landgraves held sway (the Hessian Lion), and to the Archbishops of Mainz (the wheel of Mainz).
