In music, a horn section is a group of wind instruments--sometimes dubbed "horns"--which are arranged to enhance a song or musical group. Many musical genres feature horn sections, but R&B, funk, ska, soul music and gospel music are perhaps best-known for featuring such sections.

Most horn sections feature some combination of saxophones, trumpets and trombones, with other instruments (clarinet, tuba, et cetera) sometimes utilized.

Horn sections are often anonymous, but a few have achieved prominence, such as The Memphis Horns, The Horny Horns and the Tower of Power.
