Gau-Bischofsheim is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Mainz-Bingen district in Rhineland-Palatinate, Germany.
Gau-Bischofsheim is a winegrowing village on Mainz’s southern outskirts. In the local speech the village is called Bischem. The municipality has been characterized by first being so near Mainz and also by the in parts outstanding location of the vineyards. The area under winegrowing cultivation is 76 ha. The Prince-Bishops of Mainz had their wine estates here for time out of mind. Some of the wineries bear witness to this tradition. In more recent times, proximity to Frankfurt, Wiesbaden and Mainz has led to considerable growth in Gau-Bischofsheim. A great number of clubs guide people into working towards the common good. The municipality belongs to the Verbandsgemeinde of Bodenheim, whose seat is in the like-named municipality.
The municipality’s location at the foot of the intersection of the eastern and southern slopes of the last rise in the Rhine Terrace sees to it that the climate is pleasant and sunny with below-average rainfall, without being affected by the drawbacks of the Rhine Basin’s limited air circulation. From Gau-Bischofsheim there is a good view all the way to Frankfurt and into the Odenwald. The slope in the north and west shields against strong winds and guarantees good wine.
In 769, Gau-Bischofsheim had its first documentary mention. In this document, one Rotbaldus made a donation to the Lorsch Abbey.
In the 1969 administrative reform, the Verbandsgemeinde of Bodenheim was formed out of the municipalities of Bodenheim, Gau-Bischofsheim, Harxheim, Lörzweiler and Nackenheim.
The council is made up of 17 council members, counting the part-time mayor, with seats apportioned thus:

The municipality's arms might be described thus: Per fess abased, argent two bendlets gules and gules a demi-wheel spoked of three of the first; Wheel of Mainz.
