Contemporary R&B is a popular music genre, originating from African-American musicians in the 1970s that combines rhythm and blues with elements of pop, soul, funk, hip hop, and electronic music. The incorporation of pop and electronic textures and production styles, which came to prominence since the 2010s decade, brought forth a style called electro-R&B.

The genre features a distinctive record production style and a smooth, lush style of vocal arrangement. Electronic influences and the use of hip hop or dance-inspired beats are typical, although the roughness and grit inherent in hip hop may be reduced and smoothed out. Contemporary R&B vocalists often use melisma, and since the mid-1980s, R&B rhythms have been combined with elements of hip hop culture and music, pop culture and pop music.

According to Geoffrey Himes speaking in 1989, the progressive soul movement of the early 1970s "expanded the musical and lyrical boundaries of [R&B] in ways that haven't been equaled since". This movement was led by soul singers, songwriters and producers such as Curtis Mayfield, Marvin Gaye, and Stevie Wonder. Norman Whitfield's productions at Motown, the record label of Gaye, were also pioneering for setting the soul vocals and simple hooks of earlier rhythm and blues records against strong backbeats, vocal harmonies, and orchestral sounds, all of which thickened the texture of the music. Gaye's own music on albums such as What's Going On (1971) incorporated jazz influences that led the genre into a looser musical direction.

The nearest precursor to contemporary R&B came at the end of the disco era in the late 1970s, when Michael Jackson and Quincy Jones added more electronic elements to the sound of the time, creating a smoother dancefloor-friendly style. The first result was Off the Wall (1979), which—according to Stephen Thomas Erlewine from AllMusic—"was a visionary album, that found a way to break disco wide open into a new world where the beat was undeniable, but not the primary focus" and "was part of a colorful tapestry of lush ballads and strings, smooth soul and pop, soft rock, and alluring funk".

Richard J. Ripani wrote that Janet Jackson's Control (1986) was "important to the development of R&B for several reasons", as she and her producers, Jimmy Jam and Terry Lewis, "crafted a new sound that fuses the rhythmic elements of funk and disco, along with heavy doses of synthesizers, percussion, sound effects, and a rap music sensibility." Ripani wrote that "the success of "Control" led to the incorporation of stylistic traits of rap over the next few years, and Janet Jackson was to continue to be one of the leaders in that development." That same year, Teddy Riley began producing R&B recordings that included hip hop influences. This combination of R&B style and hip hop rhythms was termed "new jack swing" and was applied to artists such as Keith Sweat, Bobby Brown, Johnny Kemp, and Bell Biv DeVoe.

Whitney Houston's The Bodyguard: Original Soundtrack Album (1992) eventually sold over 45 million copies worldwide becoming the best-selling soundtrack of all time. Janet Jackson's self-titled fifth studio album Janet (1993), which came after her multimillion-dollar contract with Virgin Records, sold over 14 million copies worldwide. Boyz II Men and Mariah Carey recorded several Billboard Hot 100 No. 1 hits, including "One Sweet Day", a collaboration between both acts, which became the longest-running No. 1 hit in Hot 100 history. Carey also released a remix of her 1995 single "Fantasy", with Ol' Dirty Bastard as a feature, a collaboration format that was unheard of at this point. Carey, Boyz II Men and TLC released albums in 1994 and 1995—Daydream.

In the late 1990s, neo soul, which added 1970s soul influences to the hip-hop soul blend, arose, led by artists such as Erykah Badu, Lauryn Hill and Maxwell. Hill and Missy Elliott further blurred the line between R&B and hip hop by recording both styles. Beginning in 1995, the Grammy Awards enacted the Grammy Award for Best R&B Album, with II by Boyz II Men becoming the first recipient. The award was later received by TLC for CrazySexyCool in 1996, Tony Rich for Words in 1997, Erykah Badu for Baduizm in 1998 and Lauryn Hill for The Miseducation of Lauryn Hill in 1999. In 1994 the singer Aaliyah dropped her debut album and in 1996 she released her second album called "One In A Million" with different sounds and produced by Missy Elliot and Timbaland, unknown at that moment. At the end of 1999, Billboard magazine ranked Mariah Carey and Janet Jackson as the first and second most successful artists of the 1990s.

Simultaneously, in the second half of the 1990s, The Neptunes and Timbaland set influential precedence on contemporary R&B and hip hop music.
