“He's The Greatest Dancer” is a song written and composed by Bernard Edwards and Nile Rodgers, and recorded by Sister Sledge for their successful 1979 album We Are Family.

"He's The Greatest Dancer" was sampled by Will Smith in his 1997 number one hit single "Gettin' Jiggy Wit' It," the first selection he released from his album Big Willie Style. In 2000, DJ Tony Touch recorded a version of the song, entitled "I Wonder Why? (He's the Greatest DJ)," whose lyrics were sung by Keisha Spivey and Pam Long of R&B girl group Total. The song was recorded and released by Dannii Minogue in 2007 and was an international Top 40 hit; it was also sampled by a Russian pop group Hi-Fi in their 1999 song "Pro Leto" (translated as "About Summer"). Robert Hood released a Techno track based on the Hook of this song on his label M-Plant. Nick Holder sampled the song on his 1997 album One Night in the Disco.

The recording features Rodgers on guitar, Edwards on bass, Tony Thompson on percussion, Raymond Jones on backing keyboards, and orchestration by Gene Orloff's Chic Strings.

Chic members Bernard Edwards and Nile Rodgers, who produced the We Are Family album for Sister Sledge, originally formulated all its songs with the group in mind, envisioning the title selection as the lead single. When Atlantic Records wanted a more overtly disco song Edwards and Rodgers gave Sister Sledge "He's The Greatest Dancer," which they had originally intended for Chic.
