{{Multiple issues| {{no footnotes|date=November 2018}} {{Unreferenced|date=April 2026}} }} '''Robert I''' (born {{ca}} 1080 – died 1120), was count of [[Aversa]] and [[prince of Capua]] from 1106, on the death of his elder and heirless brother [[Richard II of Capua]]. Robert was the second eldest son of [[Jordan I of Capua]] and [[Gaitelgrima, daughter of Guaimar IV|Gaitelgrima]], daughter of [[Guaimar IV of Salerno]].
He tried to be the papal protector as his father and grandfather had been and sent three hundred knights to rescue [[Pope Paschal II]] and his sixteen [[Cardinal (Catholicism)|cardinal]]s during their imprisonment by [[Emperor Henry V]] in 1111. However, his troops were turned back by the [[count of Tusculum]], [[Ptolemy I of Tusculum|Ptolemy I]], and never made it to their goal.
In 1114, he and [[Jordan of Ariano]] assaulted the papal principality of [[Benevento]], but the [[Landulf II, Archbishop of Benevento|Archbishop Landulf II]] made peace with them.
In 1117, Paschal II fled to him and he hosted Paschal's successor, [[Gelasius II]], later in 1118, even escorting him back to [[Rome]] with his army.
Though he did not acknowledge the [[Apulia]]n suzerainty which his brother had been forced to accept, he was nonetheless a petty secondary power in the [[Mezzogiorno]]. He died in 1120, leaving a son and successor in the infant [[Richard III of Capua|Richard III]]. A daughter of his, whose name has been lost, was married to King [[Stephen II of Hungary]] in the same year.
