Hammer (Lorde song)

"Hammer" is a song by New Zealand singer and songwriter Lorde. It was released on 20 June 2025 through Universal Music New Zealand and Republic Records as the third single from her fourth studio album, Virgin (2025). Lorde wrote and produced the song with American songwriter Jim-E Stack, with additional production from American record producer Buddy Ross. "Hammer" is a pop and R&B song instrumented by kick drums and clipped vocals. Lorde described the song as "an ode to city life and horniness" and wrote the song in late 2023 after discontinuing use of oral contraceptives. The lyrics recount the singer's exploration of her gender identity and acceptance of her general uncertainty towards life.

"Hammer" received praise from music critics, who commended the song's instrumentation and lyrical imagery. The song entered the singles chart in New Zealand at 29 and had minor chart placements in Australia, Ireland, and the United Kingdom. An accompanying music video was directed by Renell Medrano and shot in London's Hampstead Heath, where Lorde spent much of her time while writing Virgin. The video features her dancing and swimming in nature, smoking cannabis near a lake, and swinging naked in a hammock. Lorde performed "Hammer" as the opener of the Ultrasound World Tour (2025–26).
