Pons of Melgueil (c. 1075 – 1126) was the seventh Abbot of Cluny from 1109 to 1122.
Pons was the second child of Peter I of Melgueil and Almodis of Toulouse. He was descended from a noble lineage of Languedoc which had long supported the Gregorian reform. He himself was a nephew and godson of Pope Paschal II. He was an oblate at the abbey of Saint-Pons-de-Thomières, before pronouncing his vows with the Benedictines at Cluny.
Pons was elected to succeed Hugh of Semur after the latter's death. For most of his abbacy he continued Hugh's policies: the construction of the third great abbey church of Cluny ("Cluny III"), expansion of the Cluniac order into northern France and England, and mediating the Investiture Controversy between Emperor and Pope.
In 1118 the Holy Roman Emperor, Henry V, still contesting the Investiture Controversy, marched on Rome and Pope Gelasius II fled to Cluny. Before his death in 1119, Gelasius indicated that either Archbishop Guy of Vienne, or Pons of Cluny be chosen to succeed him. Guy was elected and took the name Callixtus II. Relations were strained between Rome and Cluny for a time. In 1119 Pons' government was publicly protested by Bérard de Châtillon, the Bishop of Mâcon, and Humbaud, the Archbishop of Lyon.
In the consistory of January 1120 Pope Calixtus II named Pons a cardinal-deacon. He also canonized Pons' predecessor and raised the Diocese of Santiago de Compostela to metropolitan status for the benefit of Pons' friend, Diego Gelmírez.
