Before the Police were officially disbanded, Sting began work on his first solo album late in 1984, rounding up a group of jazz musicians as a supporting band. Moving from bass to guitar, he recorded his solo debut, 1985's The Dream of the Blue Turtles, with Branford Marsalis, Kenny Kirkland, and Omar Hakim. The move wasn't entirely unexpected, since Sting had played with jazz and progressive rock bands in his youth, but the result was considerably more mature and diverse than any Police record. The album became a hit, with "If You Love Somebody Set Them Free," "Love Is the Seventh Wave," and "Fortress Around Your Heart" reaching the American Top Ten. Sting brought the band out on an extensive tour and filmed the proceedings for a 1986 documentary called Bring on the Night, which appeared alongside a live double album of the same name. That year, Sting participated in a half-hearted Police reunion that resulted in only one new song, a re-recorded version of "Don't Stand So Close to Me."

Following the aborted Police reunion, Sting began working on the ambitious Nothing Like the Sun, which was dedicated to his recently deceased mother. Proceeding from a jazz foundation, and again collaborating with Marsalis, Sting worked with a number of different musicians on the album, including Gil Evans and former Police guitarist Andy Summers. The album received generally positive reviews upon its release in late 1987, and it generated hit singles with "We'll Be Together" and "They Dance Alone." Following its release, Sting began actively campaigning for Amnesty International and environmentalism, establishing the Rainforest Foundation, which was designed to raise awareness about preserving the Brazilian rainforest. An abridged Spanish version of Nothing Like the Sun, Nada Como el Sol, was released in 1988.

Sting took several years to deliver the follow-up to Nothing Like the Sun, during which time he appeared in a failed Broadway revival of The Threepenny Opera in 1989. His father also died, which inspired 1991's The Soul Cages, a dense, dark, and complex album. Although the album peaked at number two and spawned the Top Ten hit "All This Time," the record was less successful than its predecessor. Two years later, he delivered Ten Summoner's Tales, a light, pop-oriented record that became a hit on the strength of two Top 20 singles, "If I Ever Lose My Faith in You" and "Fields of Gold." At the end of 1993, "All for Love," a song he recorded with Rod Stewart and Bryan Adams for The Three Musketeers, became a number one hit. The single confirmed that Sting's audience had shifted from new wave/college rock fans to adult contemporary, and the 1994 compilation Fields of Gold: The Best of Sting played to that new fan base.

Three years after Ten Summoner's Tales, Sting released Mercury Falling in the spring of 1996. Although the album debuted highly, it quickly fell down the charts, stalling at platinum sales and failing to generate a hit single. Although the album failed, Sting remained a popular concert attraction, a feat that confirmed his immense popularity regardless of his chart status. Released in 1999, Brand New Day turned his commercial fortunes around in a big way, though, eventually going triple-platinum and earning two Grammy Awards. Issued in 2003, Sacred Love also did well, and Sting spent several years with the reunited Police before returning to his solo game for 2009's If on a Winter's Night.... One year later, he hit the road alongside the Royal Philharmonic Concert Orchestra, who added their own symphonic arrangements to his material. Symphonicities, a companion CD, and Live in Berlin, released in conjunction with the world tour, arrived that same year.
