Junior Wells (born Amos Wells Blakemore Jr.; December 9, 1934 – January 15, 1998) was an American singer, harmonica player, and recording artist. He is best known for his signature song “Messin’ with the Kid” and his 1965 album Hoodoo Man Blues, described by the critic Bill Dahl as “one of the truly classic blues albums of the 1960s”. Wells himself categorized his music as rhythm and blues.

Wells performed and recorded with various notable blues musicians, including Muddy Waters, Earl Hooker, and Buddy Guy. He remained a fixture on the blues scene throughout his career and also crossed over to rock audiences while touring with the Rolling Stones. Not long before Wells died, the blues historian Gerard Herzhaft called him “one of the rare active survivors of the ‘golden age of the blues'”.

Wells may have been born in Memphis, Tennessee, and raised in West Memphis, Arkansas (some sources report that he was born in West Memphis). Initially taught by his cousin Junior Parker and by Sonny Boy Williamson II, Wells learned to play the harmonica skillfully by the age of seven.
