Little Head was singer-songwriter John Hiatt's fourteenth album, released in 1997. It was considered a big flop commercially as well as musically despite the fact that Hiatt and his band produced the album. It failed to hit the top half of the Billboard 200, and it was his last album with Capitol Records.
