Wigeric or Wideric was the count of the Bidgau and held the rights of a count within the city of Trier. He received also the advocacy of the Abbey of Saint Rumbold[Note 1] at Mechelen from Charles III of France. From 915 or 916, he was the count palatine of Lotharingia. He was the founder of the House of Ardennes.

Medieval historians have been unable to precisely pin down Wigeric's origins or rise to power. He possessed lands in the region of Bitburg, in the middle Moselle valley, in the Gutland, the western Eifel, and the Meuse region.[1]:16

At the death of Louis the Child, the Lotharingians rejected the suzerainty of Conrad I and elected Charles of France as their king. At the time, the military authority in Lotharingia was assigned to Count Reginar I of Hainaut , but at his death it fell to Wigeric, who became count palatine, exercising as such the military authority in Lotharingia.

Wigeric founded the monastery of Hastière now in Hastière-par-delà,[2] of which he also assumed the advocacy.

There is no historical trace of Wigeric after 919: he probably died between 916 and 919, and was buried in the monastery of Hastière.[1]
