Bobby Rush (born Emmett Ellis Jr. in Homer, Louisiana on November 10, 1933) is an American blues musician, composer, and singer. His style incorporates elements of blues, rap, and funk.

Rush has won twelve Blues Music Awards and in 2017, at the age of 83, he won his first Grammy Award for the album Porcupine Meat. He is inducted into the Blues Hall of Fame, Mississippi Musicians Hall of Fame, and Rhythm & Blues Music Hall of Fame.

Rush is the son of Emmett and Mattie Ellis. His father was a pastor whose guitar and harmonica playing provided early musical influences. As a young child he began experimenting with music using a sugarcane syrup bucket and a broom-wire diddley bow. Around 1947, he and the family moved to Pine Bluff, Arkansas, where his father took on the pastorate of a church and was a farmer.

It was here that Rush would become friends with Elmore James, the slide player Boyd Gilmore (James’s cousin), and the piano player Johnny “Big Moose” Walker; eventually forming a band to support his singing and harmonica and guitar playing. His band, Bobby Rush and the Four Jivers, consisted of Gilmore, Walker, Pinetop Perkins, and Robert Plunkett. Through Gilmore, Rush became friends with Clarksdale musician Ike Turner.
