Hype Boy

"Hype Boy" is a song by the South Korean girl group NewJeans, taken from their debut extended play (EP), New Jeans (2022). ADOR, an independent division of Hybe Corporation, released four music videos for the song on July 23, 2022, each focusing on the members and their narratives. "Hype Boy" was officially released for download and streaming as the second single of the EP on August 1, 2022.

250 and Ylva Dimberg produced "Hype Boy", while the latter wrote the lyrics with Gigi and NewJeans' member Hanni. An incorporation of future bass and pop styles, it is driven by pulsing synthesizers and distorted instrumentals that contain influences from 1990s and 2000s styles such as R&B, electronic, and moombahton. "Hype Boy" received praise from music critics for its nostalgic production style that evoked a dreamy atmosphere. NME named "Hype Boy" the best K-pop release of 2022, while NPR and Rolling Stone included it in their lists of the best songs of 2022.

The single peaked at number two on South Korea's Circle Digital Chart and reached the top 10 in Malaysia, Singapore, Taiwan, and Vietnam. The Korea Music Content Association (KMCA) certified the track double platinum for exceeding 200 million streams in South Korea, while the Recording Industry Association of Japan (RIAJ) certified the track platinum for exceeding 100 million streams in the country. "Hype Boy" also broke the record for the longest-running song on the Billboard Global 200 by a K-pop female act, charting for 42 weeks.
