John Long (born 1950), is an American country blues singer, fingerstyle guitarist, harmonica player and songwriter. He performs in a pre-war acoustic blues style, although his material is contemporary and mainly composed by Long and his elder brother. His mentor and inspiration was Homesick James. In the mid-1970s, Muddy Waters stated that Long was "the best young country blues artist playing today."
In 2017, Long was a nominee for a Blues Music Award in the 'Acoustic Album' category for his collection, Stand Your Ground. He had won the same award for his 2006 album, Lost & Found.
