The City of Olongapo (Tagalog: Lungsod ng Olongapo; Sambal: Syodad nin Olongapo) is a highly urbanized city located in the province of Zambales, Philippines. According to the latest census, it has a population of 227,270 people in 43,107 households. Unlike the rest of the Philippines which gained independence from the United States after World War II in 1946, Olongapo was governed as a part of the United States naval reservation. After lobbying efforts of James Leonard T. Gordon, the area was relinquished to the Philippine Government and converted into a municipality on December 7, 1959. The first mayor appointed was civic leader Mayor Ruben Geronimo and was later succeeded by business enterpreneur Ildefonso Arriola.
