Leslie Johnson (June 20, 1933 – August 22, 2018), better known as Lazy Lester, was an American blues musician who sang and played the harmonica and guitar. His career spanned the 1950s to 2018.

Best known for regional hits recorded with Ernie Young’s Nashville-based Excello Records, Lester also contributed to songs recorded by other Excello artists, including Slim Harpo, Lightnin’ Slim, and Katie Webster. Cover versions of his songs have been recorded by (among others) the Kinks, the Flamin’ Groovies, Freddy Fender, Dwight Yoakam, Dave Edmunds, Raful Neal, Anson Funderburgh, and the Fabulous Thunderbirds. In the comeback stage of his career (since the late 1980s) he recorded new albums backed by Mike Buck, Sue Foley, Gene Taylor, Kenny Neal, Lucky Peterson, and Jimmie Vaughan.

In the mid-1950s, Lester was on the margins of the Louisiana blues scene. According to Rolling Stone (February 23, 2006), Buddy Guy, before moving to Chicago, had played in Louisiana “with some of the old masters: Lightnin’ Hopkins, Lazy Lester, Slim Harpo.” When Guy left for Chicago, in 1957, Lester replaced him, on guitar, in a local band—even though Lester, at the time, did not own one.
