The music of Polynesia is a diverse set of musical traditions from islands within a large area of the central and southern Pacific Ocean, approximately a triangle with New Zealand, Hawaii and Easter Island forming its corners. Traditional Polynesian music is largely an inseparable part of a broader performance art form, incorporating dance and recital of oral traditions; most literature considers Polynesian music and dance together. Polynesian music expanded with colonial European contact and incorporated instruments and styles introduced through a process of acculturation that continues to the present day. Although the European tradition of hymn-singing brought by Christian missionaries was probably the most important influence, others are evident; Hawaii's influential kī hōʻalu music incorporated the Spanish guitar introduced in the late 19th century, and later introduced the steel guitar to country music. Hip hop and R&B influences have created a contemporary Urban Pasifika music genre with a strong Polynesian identity and supported by the annual Pacific Music Awards in New Zealand.

The music of Hawaii includes an array of traditional and popular styles, ranging from native Hawaiian folk music to modern rock and hip hop. Styles like slack-key guitar are well known worldwide, while Hawaiian-tinged music is a frequent part of Hollywood soundtracks. Hawaii also made a contribution to country music with the introduction of the steel guitar. In addition, the music which began to be played by Puerto Ricans in Hawaii in the early 1900s is called cachi cachi music, on the islands of Hawaii.
