"My Name Is Not Susan" was the fourth single released from Whitney Houston's third album, I'm Your Baby Tonight. The song was produced by L.A. Reid and Babyface and written by Eric Foster White. In the song, Houston confronts a lover who has mistakenly called her by his ex-girlfriend's name "Susan." She gives him a harsh rebuke for the mistake and lets him know that if he can't get over Susan, their relationship is over.

Rolling Stone's James Hunter noted that Houston "stipulates in no uncertain terms" in this song vocally.Entertainment Weekly editor David Browne panned: "in what could be seen as an audition for her pending movie career, Houston gets to act angry on My Name Is Not Susan, in which she scolds a bedmate for calling out the name of an ex-flame in his sleep." J. D. Consodine of The Baltimore Sun felt that the song was emotionless: "(Whitney) has no trouble navigating a state-of-the-art funk groove (as with the new jack "My Name Is Not Susan"), she's mainly going through the motions; there's absolutely nothing in her performance to suggest that she was even the slightest bit moved by these songs."

In the song's music video directed by Lionel C. Martin, Houston is featured playing both herself and a character named "Susan." The video is suggested by several elements in the Alfred Hitchcock film Vertigo, both containing a man involved with an obsessive love for both a glamorous blonde and down-to-earth brunette played by the same actress. Several specific scenes that are parallel include a visit to a park, dining in a restaurant, and the photographer's buying clothes for the girl, having her hair also dyed blonde, and the way she emerges from the bathroom. The boyfriend, who is a photographer may have been suggested by another Hitchcock film, Rear Window. There is also a version of the video with a remix with British rapper Monie Love.

"My Name Is Not Susan" debuted on the Billboard Hot 100 at number 67, peaking at number 20. It remained in the Top 40 for six weeks, Houston's shortest showing at the time. It peaked at number eight on the R&B Singles Chart. "My Name Is Not Susan" was modestly received internationally, where it peaked at number 29 on the UK Singles Chart and a modest number 57 in Germany. In 1998, a remixed version of the song (remixed by Snap! in 1991 as the Logic remix) charted in Germany and reached number 52, five places higher than the original did in 1991.
