Miami Sound Machine (MSM) was an American Latin pop band of Latin-influenced music that featured the vocals of Cuban-born recording artist Gloria Estefan (née Fajardo). Established in 1975 by Emilio Estefan, the band was originally known as the Miami Latin Boys before becoming the Miami Sound Machine in 1977.

The band released 13 albums and a string of hit singles until 1989. The band's 1985 album Primitive Love credited the band whereas their follow-up album Let It Loose in 1987 placed Gloria Estefan at the forefront. From 1988 to 1989, the latter album was also repackaged as Anything for You with new cover art with the international release in Europe, South Africa, Australia, and New Zealand. In 1989, the group's name ceased being included on the CD or album products—as Estefan continued as a solo artist.

In 1975, Gloria Fajardo and her cousin Mercedes "Merci" Navarro (1957–2007) met Emilio Estefan Jr. while performing at a church ensemble rehearsal. Estefan, who had formed the band The Miami Latin Boys earlier that year, learned about Fajardo through a mutual acquaintance.

While The Miami Latin Boys were performing at a Cuban wedding at Hotel Dupont, Fajardo and Navarro (who were wedding guests) performed two Cuban standards impromptu. They impressed The Miami Latin Boys so much that they were invited to join the band permanently; thereby, the band's name was changed to The Miami Sound Machine. Fajardo, who was attending the University of Miami at the time, only agreed to perform during the weekends so that her studies would not be interrupted.

In 1977, Miami Sound Machine began recording and releasing various albums and 45s on Audiofon Records in Miami, Florida. The group's primary lineup consisted of six Cuban-born Americans:

In 1977, Miami Sound Machine's first album Live Again/Renacer was released with two different covers. The group had several more releases on the Audiofon label, the RCA Victor label, and subsequently Miami Sound Machine's own label Miami Sound Machine Records. In 1978, Gloria Fajardo married Emilio Estefan Jr. after two years of dating. In 1979, Miami Sound Machine added American guitarist and native Miamian, Wesley B. Wright, and Cuban-born Fernando Garcia on trumpet (unrelated to "Kiki" Garcia).

By the end of 1979, the band was signed to Discos CBS International. Miami Sound Machine then released several albums, 45s, and twelve-inch singles beginning with the 1980 Miami Sound Machine album. The combination of traditional Latin rhythms and American R&B grooves combined with the songwriting of Gloria Estefan, "Kiki" Garcia, and Wesley B. Wright) set a crossover musical standard for the next two decades to come.

During the 1980s, with the popularity of Miami-based films and television series such as Scarface, Invasion U.S.A., and Miami Vice, the city was gaining a reputation as an exciting and notorious destination. South Beach and the remainder of Dade County was also attracting attention. NFL Miami Dolphins quarterback Dan Marino was breaking football records and adding to the Miami mystique.
