Number One Du Senegal, initially known as Star Number One, was a Senegalese band led by the band leader, Yakhya Fall.

The band was an offshoot of Star Band, a popular Senegalese band. After a fallout with one of the band's co-founders, Yakhya Fall left, and several other members followed suit. They went on to form a new band, Star Band Un.

Due to the similarity in names, there was pressure from their former band for the new band to change its moniker. The latter dropped "Star Band" and adopted "Numero Un," which they later changed to "Number One".

The band's music was  Afro-Cuban, Salsa, and mbalax.

Though Number One Du Senegal's founding members were Pape Seck, Ali Penda N'Doye, Mar Seck, and Nicolas Menheim, the band's line-up was fifteen.
