Werner, Count in Hesbaye

Werner, Count in Hesbaye (French Garnier, Latin Werinharius, short form Werinzo) (died 973) was a Lower Lotharingian count in what is now Belgium and neighbouring parts of Germany. During this period the once independent Kingdom of Lotharingia, was coming under the control of the Kingdom of East Francia, which would become the Holy Roman Empire in 962. The area was still contested by the Kingdom of West Francia.

Werner died with his brother Count Renaud, near Mons in Hainaut, now in Belgium. The two brothers were reported to have been holding the lands that had been held by one Richer, count in Luihgau and Hainaut, who had recently died, and was possibly a close relative. Werner and his brother were killed by brothers Reginar IV, the future count of Mons in Hainaut, and Lambert I, the future count of Louvain. They claimed Mons by right of their dead rebel father, Reginar III, Count of Hainaut.
