"NDA" (an acronym for "non-disclosure agreement") is a song by American singer-songwriter Billie Eilish and the fifth single from her second studio album, Happier Than Ever (2021). It is an alternative pop, dark pop, electropop, industrial, and progressive pop track, which contains elements of trip hop, techno-pop, and trance, accompanied by diverse lyrical content. Inspired by her relationships, "NDA" has lyrics about Eilish's struggle with fame and fight for privacy. Additionally, the song transitions into the following album track, "Therefore I Am". Eilish wrote the song with its producer, her brother Finneas O'Connell.
The track was released by Interscope and Darkroom Records as the album's fifth single on July 9, 2021. It is the fourth song supporting the project that impacted mainstream radio in the United States. The song received mostly favorable reviews from music critics, who often called it "dark" and "pulsating". Critics acclaimed the production and vocals, but some took issue with its themes and said it was a misplacement on Happier Than Ever's track list. Commercially, the single reached the top 20 in Australia, Canada, Greece, Ireland, Lithuania, New Zealand, Norway, and the Billboard Global 200 chart. It was certified platinum in Australia, gold in Mexico and Poland, and silver in the United Kingdom.
Eilish self-directed the music video for "NDA", which depicts Eilish walking alone on a desert road as cars race around her. It received an analysis from the critics, who saw the road representing the titular non-disclosure agreement or different parts of the singer's life. Critics said the video's atmosphere effectively accompanied the song's production and described it as dark, eerie, and moody. For further promotion, the singer performed the song numerous times for gigs like BBC Radio 1's Live Lounge, Life Is Beautiful Music & Art Festival, 2022 Coachella, and Glastonbury Festival 2022. During a 2022–2023 world tour in support of Happier Than Ever, Eilish performed the song on the stage resembling the highway road. The live rendition of the track has been featured in her concert film Happier Than Ever: A Love Letter to Los Angeles (2021).
