Sir Richard Francis Burton  (; 19 March 1821 - 20 October 1890) was a British explorer, geographer, translator, writer, soldier, orientalist, cartographer, ethnologist, spy, linguist, poet, fencer, and diplomat. He was famed for his travels and explorations in Asia, Africa and the Americas, as well as his extraordinary knowledge of languages and cultures. According to one count, he spoke 29 European, Asian and African languages.

Burton was born in Torquay, Devon, at 21:30 on 19 March 1821; in his autobiography, he incorrectly claimed to have been born in the family home at Barham House in Elstree in Hertfordshire. He was baptized on 2 September 1821 at Elstree Church in Borehamwood, Hertfordshire. His father, Lt.-Colonel Joseph Netterville Burton, of the 36th Regiment, was an Irish-born British army officer of Anglo-Irish extraction who through his mother's family - the Campbells of Tuam - was a first cousin of Lt.-Colonel Henry Peard Driscoll and Mrs Richard Graves. Richard's mother, Martha Baker, was the daughter and co-heiress of a wealthy English squire, Richard Baker (1762-1824), of Barham House, Hertfordshire, for whom he was named. Burton had two siblings, Maria Katherine Elizabeth Burton (who married Lt.-General Sir Henry William Stisted) and Edward Joseph Netterville Burton, born in 1823 and 1824, respectively.  Burton's family travelled considerably during his childhood. In 1825, they moved to Tours, France. Burton's early education was provided by various tutors employed by his parents. He first began a formal education in 1829 at a preparatory school on Richmond Green in Richmond, Surrey, run by Rev. Charles Delafosse. Over the next few years, his family travelled between England, France, and Italy. Burton showed an early gift for languages and quickly learned French, Italian, Neapolitan, and Latin, as well as several dialects. During his youth, he was rumored to have carried on an affair with a young Roma (Gypsy) woman, learning the rudiments of her language, Romani. The peregrinations of his youth may have encouraged Burton to regard himself as an outsider for much of his life. As he put it, "Do what thy manhood bids thee do, from none but self expect applause".  Burton matriculated at Trinity College, Oxford, on 19 November 1840. Before getting a room at the college, he lived for a short time in the house of Dr. William Alexander Greenhill, then physician to the Radcliffe Infirmary. Here, he met John Henry Newman, whose churchwarden was Dr. Greenhill. Despite his intelligence and ability, Burton was antagonised by his teachers and peers. During his first term, he is said to have challenged another student to a duel after the latter mocked Burton's moustache. Burton continued to gratify his love of languages by studying Arabic; he also spent his time learning falconry and fencing. In April 1842, he attended a steeplechase in deliberate violation of college rules and subsequently dared to tell the college authorities that students should be allowed to attend such events. Hoping to be merely "rusticated" - that is, suspended with the possibility of reinstatement, the punishment received by some less provocative students who had also visited the steeplechase - he was instead permanently expelled from Trinity College.
