Lili Trifilio is an American musician best known as the lead singer for the band Beach Bunny. The project began as her solo project for a number of years before being expanded to a full band in 2017, after the release of their third EP. Trifilio remains the primary creative force behind the band. Prior to Beach Bunny, Trifilio was also a member of the short-lived folk duo Fingers x Crossed with her friend Rachel Vogrich.

Outside of Beach Bunny, Trifilio has also released solo material. Her first EP, Book Club, was released in 2019. In August 2020, she created a Twitter account @mstigerlili that appeared to be teasing a musical alter ego called ​tiger lili. She would go on to release her debut single under this name the following month.
