The Meerfelder Maar is a maar by the village of Meerfeld not far from the town of Manderscheid in the Eifel in the German state of Rhineland-Palatinate.
The maar is at least 30,000 years old and, according to the more recent information, is probably even 40,000 years old. In 1978 the lake depositions were investigated in order to determine its exact age. Numerous borings have been carried out in the Meerfelder Maar right up to the present day.
