Rev. Magnifico Libre Osorio was a Filipino Methodist Pastor and human rights advocate best known for championing the rights of Indigenous people in the province of Palawan and his murder during the waning days of Ferdinand Marcos' dictatorship in the Philippines. He was not known to have political affiliations nor leanings, but his humanitarian work and the circumstances of his murder have led him to be considered a martyr of the resistance against the dictatorship, and his name is inscribed on the Wall of Remembrance at the Bantayog ng mga Bayani in Quezon City.
