Weimar is a municipality in the south of Marburg-Biedenkopf district in Gießen administrative region, Hesse, Germany.

Other than Marburg, the community also borders on Ebsdorfergrund to the east, on Fronhausen to the south, on Lohra to the southwest, and in the far west on the town of Gladenbach.

Alongside this, however, Kehna, Oberweimar and Niederweimar, simply from their names, are said to be the oldest centres in the municipal area.

Over the last few years, as the gravel quarry at Niederweimar has been expanded, great Neolithic settlements have been found, which have since been kept in protective pits.

As a result of Hesse's municipal reforms on 1 July 1974, the community was enlarged by having Argenstein (mill), Kehna (court ensemble), Nesselbrunn, Niederwalgern (Wehrkirche), Stedebach and Wolfshausen added to it.

In football, the clubs from Niederwalgern, Wenkbach, Roth and Argenstein form an association and compete as FSG Südkreis.

Table tennis can be played in, among other places, in Wenkbach in the department specially set up for it at the civic and cultural club.
