Rudolf, Count of Avernas

Count Rudolf (living 944), was a count in Lower Lotharingia, who may have held possessions in the Hesbaye region and in the area of Meuse river north of Maastricht, both in the region of present day Belgian and Dutch Limburg.

It has also traditionally been proposed that he was a son of Reginar II, Count of Hainaut, and thus a member of the so-called Regnarid dynasty.

Although there are no records which associate the brother of Reginar III clearly with any specific geographical area, counties called Avernas and Huste were counties belonging to a count or counts named Rudolf in this period, and it has been proposed that this may have been Rudolf the brother of Reginar.
