"Ill What I Bleed" is a song by American rapper Kid Cudi, first released as a promotional single on September 5, 2023 in promotion for Cudi's ninth studio album Insano (2024), and its re-issue Insano (Nitro Mega) (2024), with the single being included in the latter.^[1]

According to Cudi, the track is not intended to be the second single from the album. Instead, the release is intended to be "a lil taste from the album while u wait". The next single, "At the Party", would be released two weeks later as what Cudi said was the proper second single.^[2][3]

Chris Deville of Stereogum described the track as being darker and slower than the previous single "Porsche Topless", reminding them of ASAP Ferg.^[4] The track has also been described as being very bass-heavy.^[5]

The music video, released alongside the single's release, was directed by Kid Cudi and Jason Goldwatch. The video features Kid Cudi walking around Seoul, South Korea, dancing and smiling throughout the video.^[2][6][7] The video has been described as being very carefree and light.^[6][7]
