Anthony Edward Visconti (born April 24, 1944) is a 3× Grammy-winning American record producer, musician and singer. Since the late 1960s, he has worked with an array of performers. His first hit single was T. Rex's "Ride a White Swan" in 1970, the first of many hits in collaboration with Marc Bolan. Visconti's lengthiest involvement was with David Bowie: intermittently from 1968 to his final album Blackstar in 2016, Visconti produced and occasionally performed on many of Bowie's albums. Visconti's work on Blackstar was awarded the Grammy Award for Best Engineered Album, Non-Classical and his production of Angelique Kidjo's Djin Djin received the Grammy Award for Best Contemporary World Music Album.

Visconti was born in Brooklyn, New York, to parents of Italian descent. He started to play the ukulele when he was five years old and then learned guitar. He attended New Utrecht High School. Throughout his teenage years Visconti was involved with both a classical brass band (playing tuba) and a traditional orchestra (playing double bass), as well as playing rock-and-roll-oriented guitar, valuable experience that served him well in later years. By the age of 15, he had focused his efforts on playing in local Brooklyn bands.

After leaving school he played guitar in a band called Ricardo & the Latineers in the Catskills; the band also included Artie Butler, later a leading arranger. In 1960, he played his first recording session and over the next few years became one of the leading guitarists in New York nightclubs. He played in lounge acts, including the Ned Harvey Band and the Speedy Garfin Band, before joining a touring version of the Crew-Cuts, where he met his future wife. As Tony and Siegrid, the pair released two singles; the first, "Long Hair", was a regional hit in New York in 1966, but they could not maintain its success.

Visconti then became in-house producer for his publisher, the Richmond Organization. Through this position, in 1968, he met British producer Denny Cordell, who asked him to assist in recordings for successful jazz vocalist Georgie Fame, prompting Visconti to move to London.

One of his first production projects in England was with the British outfit Tyrannosaurus Rex (later to become T. Rex) on their debut album My People Were Fair and Had Sky in Their Hair... But Now They're Content to Wear Stars on Their Brows (1968). This began a relationship with T. Rex that would last for their next eight albums and eleven UK Top Ten singles in a row, commencing with "Ride a White Swan" (1970). One of Visconti's greatest successes was Electric Warrior (1971), the album that made T. Rex frontman Marc Bolan a superstar and cemented Visconti's producing prowess.

More early production work included David Bowie's second album (1969) and for the Welsh group The Iveys (later known as Badfinger). He produced several tracks for the Iveys' first LP, Maybe Tomorrow (1969), and Magic Christian Music (1970), released on the Beatles' Apple label.

He produced the first two albums by influential progressive rock band Gentle Giant. Shortly afterwards, Visconti began to work again with Bowie and, along with guitarist Mick Ronson and drummer John Cambridge, formed and toured with the band The Hype, in which he played bass. Although the band name would be very short-lived, most of the line-up persisted and—with Woody Woodmansey replacing Cambridge—would go on to record Bowie's album and single The Man Who Sold the World in 1970. He would further go on to work on Bowie's albums Diamond Dogs (1974), Young Americans (1975), Low (1977), "Heroes" (1977), Lodger (1979), Scary Monsters (And Super Creeps) (1980), Heathen (2002), Reality (2003), The Next Day (2013), and his final album, Blackstar (2016).

In late 1970 and early 1971, Visconti produced both the debut and second albums by UK Afrorock pioneers Osibisa. These were 1971’s self titled debut and its follow up Woyaya. Both albums also featured early examples of the artwork of Roger Dean.
