Erden is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Bernkastel-Wittlich district in Rhineland-Palatinate, Germany.
Erden lies on the Moselle’s right bank surrounded by vineyards in the great bow in the river between Bernkastel-Kues and Traben-Trarbach, where the valley spreads out into very flat country bordering on the Hunsrück. Over on the opposite bank, steep slopes lead up to the Eifel.
Erden belongs to the Verbandsgemeinde of Bernkastel-Kues, whose seat is in the like-named town.
Neighbouring places are Lösnich and Zeltingen-Rachtig, and across the river, Ürzig. The nearest middle centres are Bernkastel-Kues, some 8 km away, as the crow flies, and the district seat, Wittlich, some 10 km away. To Trier it is about 38 km.
Erden lies in a transitional zone between temperate oceanic climate and continental climate; compared to other regions in Germany, a very mild and sunny climate prevails here. In nearby Brauneberg on 11 August 1998, a record temperature of 41.2 °C in the shade, the highest ever air temperature recorded in the Federal Republic, was confirmed.
