Jonathan (died 1094) was the youngest son of Richard I of Capua. According to the Chronicon Amalfitanorum, however, he was a son of Jordan I, who was actually his brother, and married a sister of Roger I of Sicily, which may be accurate.
During the reign of his brother, he was created Count of Carinola. After Jordan's death, he defended Sora from the counts of Aquino (1091).
