Rotruda (or Roza) of Pavia (died after March 945) was the daughter of the iudex (judge) Walpert of Pavia. Her husband was Giselbert I of Bergamo.
Rotruda married Giselbert c.895. They had a son, Lanfranc I of Bergamo.
Probably after Giselbert I’s death (c.927/929), Rotruda became the mistress of Hugh of Italy, with whom she had a daughter, Rotlinda.
Because of her relationship with Hugh, Rotruda is mentioned in Liutprand of Cremona's work Antapodosis.
