I Don't Worry About a Thing is an album by American pianist, vocalist and composer Mose Allison recorded for the Atlantic label in 1962.

Allmusic awarded the album 4 stars with its review by Scott Yanow stating, "this was his breakthrough date. One of jazz's greatest lyricists, at the time, Allison was making the transition from being a pianist who occasionally sang to becoming a vocalist who also played his own unusual brand of piano. ...the set is one of Mose Allison's most significant recordings". The Penguin Guide to Jazz commented that, with its combination of material, "for some this is the classic Mose album".
