Pulau Palawan, also known as Palawan Island, is a slipper-shaped islet located just off the southwestern coast of Sentosa, south of Singapore. It lies approximately opposite Beach Station of the Sentosa Express monorail system, which is between Siloso Beach and Palawan Beach. Palawan is most likely a variant of the Malay word pahlawan, meaning "hero" or "warrior". Originally a reef known as Serembu Palawan, and marked on at least one map as "Palawan Reef", it was renamed Pulau Palawan after land reclamation. The island now has an area similar to that of Pulau Biola, about 0.4 hectares (0.99 acres).
