Desde un Principio: From the Beginning is a greatest hits album from American recording artist Marc Anthony. The album was released on November 9, 1999 by RMM Records & Video (RMM). It was a result of Anthony leaving RMM Records and signing on with Columbia Records. The recording contains twelve tracks from his years with RMM, a cover of the Rafael Hernández song "Preciosa", and two duets - one featuring Jennifer Lopez, the other featuring La India.
Allmusic's Jose Promis praised Desde un Principio: From the Beginning, calling the album an "ideal introduction" to the artist, although he complained about the songs on it being "truncated", particularly towards the end. The album received a Billboard Latin Music Award for Latin Greatest Hits Album of the Year. Desde un Principio: From the Beginning reached number one on both the Billboard Top Latin Albums and the Billboard Tropical Albums charts, and became the best-selling album of 2000 on both charts. The album was certified gold by the Recording Industry Association of America (RIAA) after shipments reached 500,000 copies.
