Berengar Fredol or Bérenger Frédol (1250 – 11 June 1323) was a French canon lawyer and Cardinal-Bishop of Frascati.
He later held the chair of canon law at the University of Bologna, and was appointed chaplain to Pope Celestine V, who in 1294 consecrated him Bishop of Béziers.
He played a prominent role in the negotiations between the pope and Philip the Fair, and attended the council held in Rome in 1302.
The same pontiff employed him in investigating the charges made against the Knights Templars, and also in the enquiry into the peculiar tenets entertained at that time by a section of the Franciscan Order.
On the death of Clement V, Fredol was proposed by the French cardinals for the vacant papal chair, but without success.
