Saint Aprus (or Aper, ; died 507) was a bishop of Toul from 500 to 507. The brother of Saint Apronia (Evronie), he was born near Trier. He may have studied as a lawyer. After entering the priesthood, Aprus was appointed bishop of Toul.
Aprus' relics were rediscovered in 978. According to the Vita Sancti Gerardi, Bishop St. Gerard I of Toul (r. 963–994) had the relics of both St. Mansuy and Aprus brought into Toul and placed in the church of St. John the Baptist while he was ill.
His feast day is 15 September.
