"Jackie Wilson Said (I'm in Heaven When You Smile)" is a song written and performed by Van Morrison and featured as the opening track on his sixth studio album, Saint Dominic's Preview. It was released by Warner Bros. in July 1972 as the first of three singles from the album and charted at number sixty-one on the US Billboard Hot 100. Both the music and lyrics are inspired by rhythm and blues singer Jackie Wilson and his song "Reet Petite", which is directly quoted in the song.
