"Of the New Day" is a song by British progressive rock band Porcupine Tree, released on 8 March 2022 as the second single in promotion of the band's eleventh studio album Closure/Continuation.

[1][2][3][4] According to front-man Steven Wilson, "Of the New Day is a song of rebirth, emerging from the darkness", further elaborating by stating how It sounds deceptively simple, a recognisably atypical Porcupine Tree ballad.

[7] Another review of the record by Thom Jurek of AllMusic enjoyed the track, stating that the track asserted itself as a "spacious ballad" that spirals into "angular prog", "blurring time signatures", and harmonics before "returning to the lithe, keyboard-centric melody".

[9] Another positive review of the track by Steview Chuck of The Guardian noted that "despite the budding sophistication of his solo work, the Wilson of Porcupine Tree remains a better musician than lyricist, but there’s a sense of chiaroscuro at play within the sensitive chord changes of Of the New Day that assures us he is no mere technical genius, and that a heart beats beneath Closure/Continuation’s flash and flair.
