Pedro Pablo Bermúdez Ascarza (27 June 1793 – 30 March 1852) was a Peruvian politician and a member of the Peruvian military. He was briefly President of Peru between January and April 1834.
His government was paralleled to that of Luis José de Orbegoso y Moncada, which was chosen as the President of the Republic. They confronted each other for control of the nation and he was defeated. He counted on the support of the marshal, Agustín Gamarra. He was exiled to Costa Rica on two occasions where he married a Costa Rican lady named Rosalía Escalante Nava, belonging to a very influential family in that country.
