公益歌曲（英语：Charity singles），常指具有慈善募款性质，或纪念特定灾难事件的歌曲，通常是合唱性质。

最早的公益歌曲出现于1979年的Music for UNICEF Concert，当中ABBA的《Chiquitita》及比吉斯的《Too Much Heaven》等名曲曾独立发行单曲唱片，其收益均全数拨捐主办该演唱会的联合国儿童基金会。而最著名的公益歌曲则要数1985年的《We Are the World》，但此后无歌曲能再创高峰。华语地区方面，第一首有纪录的公益歌曲是1985年的《明天会更好》。

A charity record (also known as a charity single) is a release of a song for a specific charitable cause.

Ex-Beatle George Harrison's "Bangla Desh" single in 1971 is commonly acknowledged as the first ever purpose-made charity single – in this case to help fund relief efforts following the 1970 Bhola cyclone and the Bangladesh Liberation War. The money raised was donated to UNICEF, as were takings from Harrison's all-star charity concert (again, the first of its kind) held at Madison Square Garden, New York, and its spin-off live album and concert film.
