The Tunasan River (Tagalog: Ilog ng Tunasan), also referred to as the Tunasan-Cuyab River, is a river system in the Philippines. This river begins in Dasmariñas, Cavite, and ends 9 kilometers later at the border of Muntinlupa City, and San Pedro, Laguna. It is one of 21 major tributaries of Laguna de Bay.[1]

The river system has six adjoining creeks:

The depth of the Tunasan currently varies from two meters to 0.25 meters

Tunasan got its name from a medicinal plant, the Opuntia tuna variety of prickly pears, which the Spanish imported from Mexico and the West Indies when they colonized the Philippines.[2]

The tunasan received media attention in 1994 and 1995 due to a series of "fishkills" caused by the high Biochemical Oxygen Demand from decomposing water lilies, and by the profusion of residential wastes that find their way into the river during the rainy season.[3]
