Reggatta de Blanc is the second studio album by the English rock band the Police, released on 5 October 1979 by A&M Records. It was the band's first release to top the UK Albums Chart and features their first two UK number-one singles: "Message in a Bottle" and "Walking on the Moon". In early 1980, the album was reissued in the United States on two 10-inch discs, one album side per disc, and as a collector's edition with a poster of the band.

The album's title loosely translates in French to "White Reggae". It was the band's second album to bear a Franglais title, after their 1978 debut album Outlandos d'Amour. Reggatta de Blanc proved more popular and successful than its predecessor. The title track earned the band their first Grammy Award for Best Rock Instrumental Performance.

In 2003, Reggatta de Blanc was ranked at number 369 on Rolling Stone magazine's list of the 500 greatest albums of all time.

Reggatta de Blanc took four weeks to record, spaced over several months. Unlike its successor, Zenyatta Mondatta, there was no pressure on the band. Of the sessions, drummer Stewart Copeland said, "We just went into the studio and said, 'Right, who's got the first song?' We hadn't even rehearsed them before we went in."

Against the wishes of A&M Records, who had wanted to equip the promising band with a bigger studio and more famous producer, the Police opted to again record at Surrey Sound with Nigel Gray. The small budget (between £6,000 and £9,000) was easily covered by the profits of their previous album, Outlandos d'Amour, further ensuring that the record label would have no control over the actual creation of the band's music.

Whereas Outlandos d'Amour had benefited from one of the most prolific songwriting periods of Sting's life, the recording sessions for Reggatta de Blanc were so short on new material that the band even considered re-recording "Fall Out" at one point. To fill in the gaps, Sting and Copeland dug up old songs they had written and used elements of them to create new songs. Much of the lyrics to "Bring On the Night" were recycled from Sting's Last Exit song "Carrion Prince (O Ye of Little Hope)" and "The Bed's Too Big Without You" similarly started as a Last Exit tune, while "Does Everyone Stare" originates from a piano piece Copeland wrote in college. The closing track "No Time This Time" was previously the B-side to "So Lonely" in November 1978, and was added to pad out the album's running time.

As on the band's first album, Reggatta de Blanc features the Police's original fusion of hard rock, British pop, reggae, and new wave music. The instrumental "Reggatta de Blanc", one of the few songs written by the Police as a group, was developed from an extended instrumental piece that the band would typically work into their live performances of "Can't Stand Losing You". "Bring On the Night" was written three years earlier as "Carrion Prince", the title taken from Ted Hughes's poem "King of Carrion", and is about Pontius Pilate; however, after reading The Executioner's Song, Sting felt that the words fitted Gary Gilmore's death wish, and says that since then, "I sing it with him in mind." "The Bed's Too Big Without You" was covered by reggae singer Sheila Hylton in 1981, and became a UK Top 40 hit.

Reggatta de Blanc continued to build on the success of Outlandos d'Amour, hitting number one on the British, Australian, and Dutch album charts upon its release in October 1979. "Message in a Bottle" and "Walking on the Moon" were released as singles and both reached number one in the UK, the band's first singles to do so. According to rock journalist Tim Peacock, with its success, the album transformed the Police "into one of the post-punk era's defining bands".
