Carlie Hanson (born May 18, 2000) is an American singer-songwriter. In 2018, she released the song "Only One", which garnered attention after being featured on a playlist curated by Taylor Swift. She released her debut extended play, Junk, in June 2019. This was followed by her 2020 extended play, DestroyDestroyDestroyDestroy. Her debut album, Tough Boy, was released in February 2022.

Hanson was born and raised in Onalaska, Wisconsin. She was inspired to become a singer by Justin Bieber and, at 14, she and a friend began posting cover songs on YouTube, hoping to follow Bieber's path.

In May 2016, while working as a cashier at McDonald's, Hanson entered a local iHeartRadio contest to see Zayn in concert. As her entry, she recorded a video of herself singing "Pillowtalk" by Zayn while sitting in a parked car outside a shopping mall. She posted the video to Instagram, and it was quickly reposted by iHeart, drawing significant attention. Hanson was subsequently contacted by a talent agent who invited her to Toronto to audition and record for producers from House of Wolf. While in Los Angeles, she worked with songwriter Dale Anthoni. In November 2017, Taylor Swift included Hanson's second single, "Only One", on an Apple Music playlist of her favorite songs. Hanson released a video for the song in March 2018, directed by Similar But Different, who assembled an all-female crew for the shoot. In April 2018, "Only One" was averaging 400,000 streams daily.
