Osbert Guy Stanhope Crawford (28 October 1886 – 28 November 1957) was a British archaeologist who specialised in the archaeology of prehistoric Britain and Sudan. A keen proponent of aerial archaeology, he spent most of his career as the archaeological officer of the Ordnance Survey (OS) and also wrote a range of books on archaeological subjects.
Born in Bombay, British India, to a wealthy middle-class Scottish family, Crawford moved to England as an infant and was raised by his aunts in London and Hampshire.
