"Can't Love You Anymore" (Hangul: 사랑이 잘; RR: Salang-i jal) is a song recorded by South Korean singer IU and Hyukoh member Oh Hyuk for IU's fourth studio album Palette (2017). Written and composed by IU, Oh Hyuk, and Lee Jong-hoon, and produced by the latter, the song served as her second pre-release single, released on April 7, 2017. The R&B influenced single offered a contrast to her previous ballad styled single in a collaboration that received much critical praise.

“Can't Love You Anymore” debuted at number three on the Gaon Digital Chart, below IU's own Through the Night and Winner's Really Really. It became the number one single in South Korea the following week, becoming IU’s 15th number one single in the country. This enabled her to extend her lead at the time over popular idol groups Big Bang, Sistar, and 2NE1, which each had nine. The song was nominated for the Mnet Asian Music Awards's Qoo10 Song of the Year and for Best Collaboration.

While an official music video for the song was never released, two performance versions were released onto YouTube.

On March 25th of 2017, the day after her lead single Through the Night was released, IU had already begun teasing "Can't Love You Anymore." Posting on her fancafe, IU stated "the second pre-release track will have a completely different feel from ‘Through the Night.’ This is a new challenge for me. It’s not a dance track, but it’s a sound that I haven’t used that much before." She also revealed that the track would feature lead singer Oh Hyuk from the band Hyukoh due to the fact she admired his vocal color. On April 4th, IU continued to tease her next single by posting the art cover online, featuring the two singers on a yellow background. The day before the song's release, IU uploaded her final teaser in the form of a short video clip of her and Oh Hyuk playfully displaying their friendship and encouraging people to listen to the song the following day. The song was finally released the Friday of April 7th, 2017 at 6pm KST.
