"Driftin' Blues" or "Drifting Blues" is a blues standard, recorded by Johnny Moore's Three Blazers in 1945. The song is a slow blues and features Charles Brown's smooth, soulful vocals and piano. It was one of the biggest blues hits of the 1940s and "helped define the burgeoning postwar West Coast blues style". "Driftin' Blues" has been interpreted and recorded by numerous artists in various styles. The Blues Foundation Hall of Fame and the Rock and Roll Hall of Fame have acknowledged the influence and lasting popularity of the song.

Tony Russell "Charles" Brown was an American singer and pianist whose soft-toned, slow-paced nightclub style influenced West Coast blues in the 1940s and 1950s. Between 1949 and 1952, Brown had seven Top 10 hits in the U.S. Billboard R&B chart. His best-selling recordings included "Driftin' Blues" and "Merry Christmas Baby".
