Beach Bunny is an American rock band formed in 2015 by Lili Trifilio in Chicago, Illinois. The group achieved widespread popularity after their song "Prom Queen" went viral on TikTok.

Beach Bunny began as a bedroom-based solo project in 2015 when Lili Trifilio recorded a song titled "6 Weeks". The same year, Trifilio released her first EP, titled Animalism. She released her second EP titled Pool Party in 2016. In 2017, she released her third EP titled Crybaby, and Beach Bunny expanded to a full four-piece lineup shortly after. In 2018, Beach Bunny released her fourth EP, titled Prom Queen.

On October 31, 2019, Trifilio and the band announced that they had signed to Mom + Pop Music and released their first full-length album, Honeymoon, on February 14, 2020. The album was produced by Joe Reinhart at Electrical Audio; the Chicago studio owned by Steve Albini, and subsequently mixed at Reinhart's Headroom Studios. Honeymoon was met with widespread critical acclaim, appearing on the Best Albums of 2020 lists in both The New York Times, and Rolling Stone. The album contained the song "Cloud 9", which became the band's second song to go viral on TikTok, where it was used in 2 million videos.
