Light music is a generic term applied to a mainly British musical style of "light" orchestral music, which originated in the 19th century and had its heyday during the early to mid part of the 20th century, although arguably it lasts to the present day.

The style is a less "serious" form of Western classical music, featuring through-composed, usually shorter orchestral pieces and suites designed to appeal to a wider audience than more serious compositions. The form was especially popular during the formative years of radio broadcasting, with stations such as the BBC Light Programme featuring a playlist largely consisting of light compositions.

Occasionally known as mood music or concert music, light music is often grouped with the easy listening genre, although this designation is misleading. Although mainly a British phenomenon, light music was also popular in the U.S. and Europe, and many compositions in the genre are still familiar through their use as film, radio and television themes.
