Saint Rimbert or Rembert (Flanders, *830 – 11 June, 888*, in Bremen) was archbishop of Bremen-Hamburg from 865 until his death.

A monk in Turholt (Torhout), he shared a missionary trip to Scandinavia with his friend Ansgar, whom he later succeeded as archbishop in Hamburg-Bremen in 865. He also wrote a biography about Ansgar, Vita Ansgari.

Rimbert is revered as a saint particularly in Friesland. His feast day is 4 February.
