Owen Stanley Range is the south-eastern part of the central mountain-chain in Papua New Guinea. It was seen in 1849 by Captain Owen Stanley while surveying the south coast of Papua and named after him. Strictly, the eastern extremity of the range is Mount Victoria 4,038 metres (13,248 ft), which was climbed by Sir William Macgregor in 1888, and it extends as far west as Mount Thynne and Lilley. But the name is generally used to denote the whole of the chain of the Papuan Peninsula, from Mount Chapman 3,376 metres (11,076 ft) to the south-eastern end of the island, and to include Mount Albert Edward 3,990 m (13,091 ft) which is really separated from it by the Wharton Chain.
