Notker (or Notger) of Liège (Latin: Notgerus; c. 940 – 10 April 1008 AD) was a Benedictine monk, bishop (972–1008) and first prince-bishop (980–1008) of the Bishopric of Liège (now in Belgium). 
In Folcwin's opinion Notker's achievements surpass those of any of his predecessors. He developed the urban structure of the city, its fortifications, commerce and education. Under his rule, the city of Liège was sometimes called the "Northern Athens".
