Elvis Aaron Presley (January 8, 1935 – August 16, 1977), known mononymously as Elvis, was an American singer and actor. Known as the "King of Rock and Roll", he is regarded as one of the most significant cultural figures of the 20th century. Presley's energized performances and interpretations of songs, and sexually provocative dance moves, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, brought both great success and initial controversy.

Presley was born in Tupelo, Mississippi; his family relocated to Memphis, Tennessee, when he was 13. His music career began there in 1954, at Sun Records with producer Sam Phillips, who wanted to bring the sound of African-American music to a wider audience. Presley, on guitar and accompanied by lead guitarist Scotty Moore and bassist Bill Black, was a pioneer of rockabilly, an uptempo, backbeat-driven fusion of country music and rhythm and blues. In 1955, drummer D. J. Fontana joined to complete the lineup of Presley's classic quartet and RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who managed him for the rest of his career. Presley's first RCA Victor single, "Heartbreak Hotel", was released in January 1956 and became a number-one hit in the US. Within a year, RCA Victor would sell ten million Presley singles. With a series of successful television appearances and chart-topping records, Presley became the leading figure of the newly popular rock and roll; though his performative style and promotion of the then-marginalized sound of African Americans led to him being widely considered a threat to the moral well-being of white American youth.

In November 1956, Presley made his film debut in Love Me Tender. Drafted into military service in 1958, he relaunched his recording career two years later with some of his most commercially successful work. Presley held few concerts, however, and guided by Parker, proceeded to devote much of the 1960s to making Hollywood films and soundtrack albums, most of them critically derided. Some of Presley's most famous films included Jailhouse Rock (1957), Blue Hawaii (1961), and Viva Las Vegas (1964). In 1968, he returned to the stage in the acclaimed NBC television comeback special Elvis, which led to an extended Las Vegas concert residency and a string of highly profitable tours. In 1973, Presley gave the first concert by a solo artist to be broadcast around the world, Aloha from Hawaii. However, years of prescription drug abuse and unhealthy eating severely compromised his health, and Presley died unexpectedly in August 1977 at his Graceland estate at the age of 42.

Presley is one of the best-selling music artists of all time, with sales estimated around 500 million records worldwide. He was commercially successful in many genres, including pop, country, rockabilly, rhythm and blues, adult contemporary, and gospel. He won three Grammy Awards, received the Grammy Lifetime Achievement Award at age 36, and has been inducted into multiple music halls of fame. He holds several records, including the most RIAA-certified gold and platinum albums, the most albums charted on the Billboard 200, the most number-one albums by a solo artist on the UK Albums Chart, and the most number-one singles by any act on the UK Singles Chart. In 2018, Presley was posthumously awarded the Presidential Medal of Freedom.
