Gilbert (or Giselbert) (c. 890 – 2 October 939) was the duke of Lotharingia (or Lorraine) until 939. The beginning of the reign of Gilbert is not clear. A dux Lotharingiae is mentioned in 910 and this may have been Gilbert. Lotharingia sided with Charles III in 911 who was deposed in West Francia in 922 by Robert but remained king in Lotharingia from where he tried to reconquer West Francia until being imprisoned in 923.
