Pedro Calungsod (Spanish: Pedro Calúñgsod or archaically Pedro Calonsor; mid-1650s – April 2, 1672), also known as Peter Calungsod and Pedro Calonsor, was a Catholic Filipino migrant, sacristan and missionary catechist who, along with the Spanish Jesuit missionary Diego Luis de San Vitores, suffered religious persecution and martyrdom in Guam for their missionary work in 1672.While in Guam, Calungsod preached Christianity to the Chamorro people through catechesis, while baptizing infants, children, and adults at the risk and expense of being persecuted and eventually murdered. Through Calungsod and San Vitores's missionary efforts, many native Chamorros converted to Roman Catholicism.

Calungsod was beatified on March 5, 2000, by Pope John Paul II, and canonized by Pope Benedict XVI at Saint Peter's Basilica in Vatican City on October 21, 2012.
