Captain Owen Stanley FRS RN (13 June 1811 – 13 March 1850) was a British Royal Navy officer and surveyor.
Stanley was born in Alderley, Cheshire, the son of Edward Stanley, rector of Alderley and later Bishop of Norwich. A brother was Arthur Penrhyn Stanley and his sister Mary Stanley.
He entered the Royal Naval College at the age of fifteen, and for nine years served under Phillip Parker King on HMS Adventure and John Franklin in the Mediterranean. In 1836 he sailed to the Arctic as scientific officer on HMS Terror under George Back. In 1838 he was given command of HMS Britomart and sailed to Australia and New Zealand, returning in 1843. In March 1842 he was elected a Fellow of the Royal Society 
In December 1846 Stanley sailed from Portsmouth in charge of HMS Rattlesnake, with the naturalists Thomas Huxley and John MacGillivray on board. In November 1847 he arrived at Port Curtis on the Australian coast, and after surveying the harbour described it as a very good anchorage. In 1848 he continued further north to survey New Guinea, and in June of that year offered protection and assistance to Edmund Kennedy's expedition to the Cape York Peninsula. Owen went on to survey the Louisiade Archipelago but in 1849 fell ill, and died in March 1850 after returning to Sydney.
In memory of his brother, Dean Stanley of Westminster Abbey donated the font in ChristChurch Cathedral, Christchurch.
The Owen Stanley Range in New Guinea is named after him.
