Peter Egerton Warburton (1813—1889) was an English naval and military officer who became famous as an explorer of Australia. He served as the Commissioner of Police in South Australia. He was employed by the South Australian government to replace Benjamin Herschel Babbage, because they felt Babbage was moving to slowly. Warburton led several trips into the desert between 1856 and 1874. He found a gap through the ring of salt lakes north of Adelaide in South Australia, which had blocked northward exploration. He visited the artesian springs which he named Coward Springs. He also explored the Davenport Range which he named after Sir Samuel Davenport, a South Australian politician.
