"Supalonely" is a song by New Zealand singer Benee featuring American singer Gus Dapperton, released through Republic Records on 6 December 2019 as the third and final single from her second extended play Stella & Steve (2019).^[2][3] It also appears on Benee's debut studio album, Hey U X (2020). The song gained immense popularity on the online video-sharing platform TikTok in March 2020, gaining more than 6.9 billion plays for the month.^[4][5][6] It peaked on the top 40 in over 25 countries including the United Kingdom, the United States, Australia, Canada, France, Germany, The Netherlands and New Zealand, earning a gold certification in its second week in the latter.

The Straits Times also credited the success of "Supalonely" to be owed to those who resonated with the song's themes at the height of the COVID-19 pandemic lockdowns, which were ongoing at the time of the song's popularisation.^[7]

"Supalonely" was written during a month-long trip to Los Angeles. It was inspired by her breaking up with her boyfriend, and was written as a song where she could mock her own sadness.^[8] The song "Blu" from Stella & Steve was recorded the day after "Supalonely" during the Los Angeles trip, and was inspired by the same break-up.^[9]

Up to three versions of the song exist: the explicit version, the clean version which omits the f-word and replaces the b-word with "chick",^[10] and another that completely omits Gus Dapperton's verses and skips straight to the outro after the second chorus.
