"Expression" is a song by American group Salt-N-Pepa, released in November 1989 by Next Plateau as the lead single from their third album, Blacks' Magic (1990). The song was both written and produced by member Cheryl "Salt" James. It became the group's second single to reach the top 40 in the United States, peaking at number 28 on the Billboard Hot 100 while also topping the Billboard Hot Rap Singles chart, becoming their first song to do so. The single was certified platinum by the Recording Industry Association of America (RIAA). In 1992 a re-release as the first (and only) single from Salt-N-Pepa's remix album, Rapped in Remixes: The Greatest Hits Remixed, charted within the top 30 in Ireland and the United Kingdom and peaked at number 13 in France. The accompanying music video is notable for marking the directorial debut of director Millicent Shelton.
