II; Spanish: Pedro II; born Manuel Alonso Corral; 22 November 1934 – 15 July 2011), also known by the religious name Isidoro María de la Santa Faz, was the second Pope of the Palmarian Catholic Church, who in this capacity, claimed to be the 264th Pope of the Catholic Church from 21 March 2005 until his death on 15 July 2011.

Corral was a lawyer, but he left his legal practice to join Clemente Domínguez y Gómez, who founded the Carmelite Order of the Holy Face in 1975.

In 1978, Domínguez claimed that Jesus Christ created him pope in 1978 in a mystical vision and transformed the Order into the Palmarian Catholic Church.

This appointment – instead of leaving this decision to a Palmarian College of Cardinals – contributed to a rift in the church.

After his death, Corral was canonised on 17 July 2011 by his successor, Gregory XVIII, and has subsequently been referred to by adherents of his church as "Pope Saint Peter II the Great".
