"All by Myself" is a song by Brazilian DJ Alok, English DJ Sigala, and English singer and songwriter Ellie Goulding. It was released through Sony Music on 7 October 2022. The song was written by Alok, Andrew Wells, Anthony Rossomando, Goulding, Martin Gore, OhYes, and Tom Mann, and produced by Alok, Sigala, OhYes, and Wells. It appears in the deluxe edition of Goulding's fifth studio album, Higher Than Heaven (2023). An accompanying music video was released on 12 December 2022.
Alok started working on the song in 2021 using Goulding's vocals; however, he stopped as it was not turning out the way he wanted. He then revisited the song and decided to use a sample of Depeche Modes 1990 song "Enjoy the Silence". After obtaining sample clearance from the band, he finished working on the song with Sigala's help. On 4 October 2022, Alok announced the collaboration along with its cover artwork and release date on his social media accounts.
