Pulau Ujong (Malay: literally 'island at the end [of the peninsula]') or Singapore Island is the main island of the island country of Singapore. It forms the majority of the island country in terms of area and population.[clarification needed] With a population of 5,076,700 and an area of 710 square kilometres, Pulau Ujong is the 21st most populous island in the world and the 29th most densely populated island in the world. Its highest point is Bukit Timah at 165 metres.
It was the easiest reference to the Singapore Island as anyone travelling from the Straits of Malacca to the South China Sea or vice versa would have to pass the island, hence giving it the name. Like Johor's old name, Ujong Tanah meaning "Land's End", the island was known better by the Orang laut as Pulau Ujong literally meaning "End Island". The 3rd-century Chinese reference to Pu Luo Chung (蒲罗中）corresponds to the Malay reference known as Pulau Ujong.
According to a third-century book Record of Foreign countries during the Eastern Wu Period (吴时外国传), Pu Luo Jong (Pulao Ujong) was inhabited by cannibals with five to six inch tails.
