Famous Last Words (My Chemical Romance song)

"Famous Last Words" is a song by the American rock band My Chemical Romance from their third studio album, The Black Parade (2006). Originally titled "The Saddest Music in the World", the track was written by the band following Mikey Way's premature departure from the album's writing sessions due to mental health issues. While the lyrics were initially about Gerard Way's criticisms of Mikey's decision, they eventually broadened out to be about the band as a whole, and took on themes of optimism and making the most out of life. Compositionally, "Famous Last Words" is an upbeat hard rock, emo and pop song. It was written by band members Bob Bryar, Frank Iero, Ray Toro, Gerard Way, and Mikey Way, and was produced by the group alongside Rob Cavallo.

"Famous Last Words" was initially released as the last song on The Black Parade, and was officially released as the album's second single on January 22, 2007. The single has charted in multiple countries, including in the United Kingdom where it topped the UK Rock & Metal Singles Chart and reached number 8 on the UK singles chart. It was certified platinum by the British Phonographic Industry (BPI) in 2025. "Famous Last Words" also charted in the United States, where it reached number 4 on the Alternative Airplay chart and number 88 on the Billboard Hot 100. In 2025, it was certified as two-times platinum by the Recording Industry Association of America (RIAA). The track has also been certified platinum by Recorded Music NZ (RMNZ).

A music video for "Famous Last Words" was released on January 11, 2007. Recorded directly after the one for "Welcome to the Black Parade", it features the band performing the track while the set burns down around them. The track received generally positive reviews from music critics, and has been identified as a standout in both The Black Parade and the band's discography as a whole. "Famous Last Words" was included on the setlist of the Black Parade World Tour, the band's 2007–2008 concert tour in support of The Black Parade, and has been featured in multiple later live performances.
