"Cloak n Dagger" is a song by the American musicians Glaive and Ericdoa from their collaborative extended play (EP), Then I'll Be Happy (2021).

It is a fast-paced rap, pop, and emo song driven by retro synth layers, a hazy instrumental, and drums.

"Cloak n Dagger" received positive reviews from critics; some thought it was a standout on Then I'll Be Happy and others highlighted the song's hook.

[5] The music video was shot on film and contains cameo appearances from the song's producers, Glasear, Kimj, and Whethan.

[2] The song was written about removing a harmful person from your life;[6] Alphonse Pierre of Pitchfork called it a "two-sided lovesick anthem".

He also highlighted the track's "off-the-cuff arrangements", called the songwriting confessional, and commented that the lyrics "could be read as rap or emo".

[11] Justin Curto from Vulture thought that "the chorus is the reason to come back", and that "Hearing [Glaive] and [Ericdoa] savor every curse and insult will just make you want to shout along with them".

Writing about "Cloak n Dagger" and the EP's second single "Fuck This Town", he called the songs "thoughtful genre explorations that subvert norms instead of succumbing to them".
