"Always and Forever" is an R&B song written by Rod Temperton and first recorded by the British-based multinational funk-disco band Heatwave in 1976. Released as a single in 1977, the song is included on Heatwave's debut album Too Hot to Handle and has been covered by numerous artists.

After the international success of Heatwave's debut single, the disco song "Boogie Nights", "Always and Forever" was chosen as the U.S. follow-up single in late 1977. A ballad featuring lead vocals by Johnnie Wilder, Jr., "Always and Forever" stood out among the band's predominantly disco repertoire and became a successful U.S. hit song in early 1978. It reached #18 on the Billboard Hot 100 in March of that year after peaking at #2 on the Billboard R&B chart, the band's highest showing on that tally. The single was certified platinum by the RIAA. In the UK, the songs "Too Hot to Handle" and "The Groove Line" were released before a double A-sided "Always and Forever" / "Mind Blowing Decisions" was issued in November 1978. This became the band's second top ten on the UK Singles Chart when it spent two weeks at #9 in December of that year.

In the late 1970s through the 1980s it was a popular "slow dance" song at high school proms, particularly in inner-city areas with a high minority population. The song was also played during the slow dance scene in the movie House Party.

In the liner notes to Heatwave's 1996 compilation album The Best of Heatwave: Always and Forever, music writer and former Billboard contributor Brian Chin notes that Wilder "says that it was right around the time of the single release of "Always and Forever" that he knew Heatwave's music would stand the test of time. This pop standard is emblematic of the Heatwave fusion of influences - R&B, teen romance, and both European and American flavors of pop." AllMusic reviewer Craig Lytle states that the song "was and continues to be an ageless piece. Johnnie Wilder's vocal exhibition throughout the vamp is breathtaking."
