Miles Parks McCollum (born August 23, 1997), known professionally as Lil Yachty, is an American rapper. He first gained recognition in August 2015 for his viral hit "One Night", the lead single from his debut extended play (EP), Summer Songs. He released his debut mixtape Lil Boat in March 2016, and signed a joint venture record deal with Motown, Capitol Records, and Quality Control Music in June of that year.

His debut studio album, Teenage Emotions (2017), peaked at number five on the Billboard 200 despite mixed critical response. His second album, Lil Boat 2 (2018), peaked at number two on the chart, while his third, Nuthin' 2 Prove (2018), peaked at number 12; both were met with continued unfavorable critical reception. His fourth album, Lil Boat 3 (2020), peaked at number 14, while his fifth album, Let's Start Here (2023), marked a departure from hip hop in favor of psychedelic rock, and received critical praise. His collaborative album with English singer James Blake, Bad Cameo (2024), further experimented with the genre and was met with continued praise despite failing to chart.

McCollum is also notable for his features on the 2016 singles "Broccoli" by DRAM and "ISpy" by Kyle. His cherry-red hairstyle, lighthearted tone, and optimistic image are also centers of mainstream attention. Yachty was nominated for a Grammy Award for his work on "Broccoli".
