"Not the End of the World" is a song by American singer Katy Perry from her sixth studio album Smile (2020). It was released on December 21, 2020, by Capitol Records as the third single from the album. It was written by the singer, Michael Pollack, Madison Love, Jacob Kasher Hindlin, and Andrew Goldstein, and was produced by Goldstein and Oscar Görres. Built off the interpolation of a melody from Steam's 1969 song "Na Na Hey Hey Kiss Him Goodbye", it is a techno-pop and trap-pop track with an underlying disco and techno beat. A self-empowerment cut, with the lyrics about positivity and Perry's indifference to her critics. Compared to her 2013 single "Dark Horse", the song left music commentary divided. Some of them depreciated the single's message in the context of the COVID-19 pandemic.
