Mas Flow is the debut compilation album by reggaeton producers Luny Tunes. Along with Tego Calderón's El Abayarde, also released in 2003, Mas Flow was the first reggaeton album to meet a mass audience. In doing so, it introduced the world not only to the musical style itself in album format, but also to Luny Tunes, the production duo who would quickly become one of reggaeton's best known producers. The mixtape nature of Mas Flow helped introduce a host of notable reggaeton vocalists in the process, including Daddy Yankee, Don Omar, Tego Calderón, Wisin & Yandel, Héctor & Tito, Nicky Jam, Baby Ranks, Zion & Lennox, and others. The album's success led to the release of Mas Flow 2.
