Kim Petras (, German: [ˈpeːtʁas]; born 27 August 1992) is a German singer and songwriter based in Los Angeles. Between 2016 and 2020, she released music as an independent artist under her own imprint, BunHead Records, before signing with Amigo and Republic Records in 2021.

Petras began recording music as a teenager. Prior to releasing a full-length project, she independently released various singles from 2017 to 2019, including "I Don't Want It at All", "Heart to Break" and "1, 2, 3 Dayz Up", and has coined this series of singles as "Era 1". Several of these singles charted on Billboard's Dance/Electronic Songs chart. In 2019, Petras independently released her first two full-length projects, Clarity and Turn Off the Light.

Petras signed with Republic Records in 2021 and released the EP Slut Pop, her first project with Republic, the following year. Petras's collaborative 2022 single "Unholy" with Sam Smith topped charts internationally, including the UK Singles Chart and the Billboard Hot 100, making her the first openly transgender solo artist to reach number one in the United States. Petras was the first openly transgender artist to receive a Grammy Award for Best Pop Duo/Group Performance (for "Unholy" in 2023) and the second transgender woman to win a Grammy following Wendy Carlos.
