Program music or programmatic music is a type of instrumental art music that attempts to musically render an extramusical narrative. The narrative itself might be offered to the audience through the piece's title, or in the form of program notes, inviting imaginative correlations with the music. A well-known example is Sergei Prokofiev's Peter and the Wolf.

The genre culminates in the symphonic works of Richard Strauss that include narrations of the adventures of Don Quixote, Till Eulenspiegel, the composer's domestic life, and an interpretation of Friedrich Nietzsche's philosophy of the Übermensch. Following Strauss, the genre declined and new works with explicitly narrative content are rare. Nevertheless the genre continues to exert an influence on film music, especially where this draws upon the techniques of 19th-century late romantic music. Similar compositional forms also exist within popular music, including the concept album and rock opera.

The term is almost exclusively applied to works in the European classical music tradition, particularly those from the Romantic music period of the 19th century, during which the concept was popular, but pieces which fit the description have long been a part of music. The term is usually reserved for purely instrumental works (pieces without singers and lyrics), and not used, for example for opera or lieder. Single-movement orchestral pieces of program music are often called symphonic poems. Absolute music, in contrast, is intended to be appreciated without any particular reference to the outside world.
