"Mary Ann" is a song written and performed by Ray Charles and released in 1956 as a single on the Atlantic Records label. It was the third Ray Charles song to reach No. 1 on the Billboard Best Selling Rhythm & Blues chart. The song is set to a Latin beat, but switches into a swing rhythm, "an alternation that adds fun for the dancers." It has been described as "a sexy blues," and "a lightly lascivious tune."
