Raino, also Rayno, Ranulf, or Reginulf (died after 1179), was the last count of Tusculum from an unknown date when he was first associated with his elder brother, Jonathan, to his own death.
Raino called in the aid of Rainald of Dassel, the archchancellor of Italy and archbishop of Cologne.
With 1,300 Germans and Brabantines and the men of Robert II of Bassunvilla, Christian encamped beside Monte Porzio outside the city.
The last count of Tusculum was thus removed from his office and even denied entry into his newly acquired towns.
By a treaty with Cencius and Oddone Frangipane, he obtained Terracina and Circegium in exchange for Tusculanum and Monte Cavo.
