"I Don't Care Anymore" is a song written, performed, and produced by English drummer Phil Collins (with co-production by Hugh Padgham). It is the third single from Collins' second solo album, Hello, I Must Be Going! (1982). It is one of the artist's most recognisable signature songs, and a favourite of many Collins fans worldwide.

This song is considered 'dark' in tone, and is comparable to Collins' earlier hit single "In the Air Tonight", as both contain powerful drum kit along with simplistic synthesizers and guitar riffs, coupled with angry lyrics directed at Collins' failed first marriage. The drums also illustrate the gated reverb recording technique that defined Collins' sound throughout the 1980s. During "I Don't Care Anymore", the drum track switches several times between "standard" studio sound and a gated reverb overlay. The song earned Collins his first Grammy Award nomination for Best Male Rock Vocal Performance in 1984, but lost to Michael Jackson's "Beat It".
