"Go to Sleep" is a song by Belgian singer Loïc Nottet, released on 22 December 2017 for digital download by Sony Music Entertainment.

Music critics gave positive reviews of "Go to Sleep", praising the song's message and nature, as well as Nottet's vocal delivery.

An accompanying music video was uploaded onto Nottet's YouTube channel simultaneously with the single's release, and was directed by Sidney van Wichelen.

[7] Christophe Segard, writing for website Aficia, praised the "power and softness" of "Go to Sleep" and commended Nottet's vocal delivery.

[6] Jonathan Vautrey of Wiwibloggs likened the track to material released by Australian singer Sia, particularly "Snowflake" from her eight studio album Everyday Is Christmas (2017).

[7] Although also praising the choreography, Segard of Aficia criticized "the square format of the clip and its staging [as] too poor" in comparison to the maximalist production of Nottet's previous visual for "Doctor" (2017).
