The Middle Magdalena Valley, Middle Magdalena Basin or Middle Magdalena Valley Basin (Spanish: Valle Medio del Magdalena, VMM) is an intermontane basin, located in north-central Colombia between the Central and Eastern Ranges of the Andes. The basin, covering an area of 34,000 square kilometres (13,000 sq mi), is situated in the departments of Santander, Boyacá, Cundinamarca and Tolima.
The basin is structurally bounded by the Palestina Fault to the west and the Bucaramanga Fault to the east. The Middle Magdalena Valley hosts the middle course of the Magdalena River, the main river of Colombia, flowing from the Upper Magdalena Valley in the south to the Lower Magdalena Valley to the northwest. The basin is elongated with an approximate width of 80 km (50 mi) and extends to the north for approximately 450 km (280 mi), where it terminates against the Santander Massif and Cesar Valley. To the south, it terminates against the Upper Magdalena Valley, which consists of the Girardot and Neiva Sub-basins where the Central and Eastern Ranges converge.
The basin is an important producer of oil in Colombia, with main fields Yariguí-Cantagallo, Moriche, Casabe, La Cira-Infantas, Velásquez, Santos, Palagua, Teca, Payoa and Lisama. The first three fields were among the twenty most producing fields of Colombia in 2016. Until 2008, La Cira-Infantas and Casabe produced more than 730 million barrels (116×106 m3) and 289 million barrels (45.9×106 m3) respectively. Main producing reservoirs are the Colorado, Mugrosa, Esmeraldas and La Paz Formations. Secondary reservoirs are Lisama and La Luna.
