The Upper Marikina River Basin Protected Landscape is a protected area in the Province of Rizal in the Philippines, which forms the upper area of the drainage basin of the Marikina River.

The term "Marikina Watershed" is sometimes used to specifically refer to this protected area, but is also generally to the river's entire drainage basin, from the Sierra Madre Mountains of Rizal Province all the way to the Napindan area in Pasig, where its mouth empties into the Pasig River.

The Upper Marikina River Basin Protected Landscape had been named the Marikina Watershed Reservation until November, 2011, when President Benigno S. Aquino III upgraded its status from "reservation" to "protected landscape."
