"Hot Fun in the Summertime" is a 1969 song recorded by Sly and the Family Stone. The single was released in the wake of the band's high-profile performance at Woodstock, which greatly expanded their fanbase. The song peaked at number 2 on the U.S. Billboard Hot 100 pop singles chart and number 3 on the U.S. Billboard soul singles chart in autumn 1969. It is ranked as the seventh biggest U.S. hit of 1969, and the 65th in Canada.
Thematically, "Hot Fun in the Summertime" is a dedication to the fun and games to be had during the summer. "Hot Fun in the Summertime" was intended to be included on an in-progress album with "Everybody Is a Star" and "Thank You (Falettinme Be Mice Elf Agin)"; the LP was never completed, and the three tracks were instead included on the band's 1970 Greatest Hits LP. This song is known for its rare use of strings in a Sly and the Family Stone song, featuring violins being played in the upper register.
The B-side to this single is "Fun," a song taken from the group's third album (Life) from 1968.
The track was covered by the Beach Boys on their 1992 album Summer in Paradise. The song was also released as a single during that same year, backed with "Summer of Love." A video was made to accompany the song.
