Robert of Rouen (died before 1112) was the first bishop of Lydda and Ramla from 1099.
Born in the Roman Catholic Archdiocese of Rouen, Robert was a Norman cleric who joined the First Crusade.
[1][2] The crusaders took possession of Ramla without fight on 30 June 1099, because the Muslim garrison had left it.
[2] The nearby Church of Saint George was an important shrine at Lydda and the crusaders decided to establish a Roman Catholic bishopric in the town.
[4] Being the only Roman Catholic bishop in Palestine, Robert consecrated Daimbert of Pisa as the Latin Patriarch of Jerusalem on Christmas Day in 1099.
