Saint Bernard is a fourth class municipality in the province of Southern Leyte, Philippines. According to the 2010 census, it has a population of 25,169 people in 30 barangays. It is situated on the Pacific coast and the first town form the mountain road from the eastern side of Sogod Bay.
This town was formerly the largest barrio of San Juan, then known as "Himatagon". On December 9, 1954, President Ramon Magsaysay issued Executive Order No. 84, converting the barrio as a municipality of Saint Bernard. It was through the efforts of Leyte Governor Bernardo Torres that the conversion was made possible in response to the lingering clamour of the inhabitants for an independent and separate municipality from San Juan.
On February 17, 2006, a tragic series of mudslides killed over 1100 residents in Barangay Guinsaugon. Affected families were treated by the Philippine government and other non-government organizations from all over the world. New houses were built, and the people chose New Guinsaugon as the name of their village located near the town proper.
