The MAMA Award for Song of the Year (Korean: 올해의 노래상; RR: Olhaeui noraesang) is an honor presented at the annual MAMA Awards, a South Korean awards ceremony presented by Mnet. One of the event's four most prestigious daesang (or grand prize) awards, it was first awarded during the ceremony's eighth edition in 2006—then titled the Mnet KM Music Festival. Having gone through various name changes since its inaugural ceremony in 1999, it was renamed the Mnet Asian Music Awards from 2009 until it was rebranded as the MAMA Awards in 2022.
