Polifonia (kutoka Kigiriki poli, yaani nyingi + fonia, yaani sauti; kwa Kiingereza "polyphony") ni mtindo wa kuimba kwa sauti nyingi pamoja bila ya kuvurugana, bali kwa kulingana vizuri. Polifonia imestawi sana Afrika kusini kwa Sahara tangu zamani, halafu kwa utaalamu zaidi Ulaya wakati wa karne za kati, renaissance na baroko.
