The Velikaya () is a river in Novosokolnichesky, Pustoshkinsky, Sebezhsky, Opochetsky, Pushkinogorsky, Ostrovsky, Palkinsky, and Pskovsky Districts of Pskov Oblast, as well as in the city of Pskov in Russia. It is the largest tributary of Lake Peipus and belongs to the drainage basin of the Narva. It is 430 km long, and the area of its basin 25200 km2. The name of the river literally means "Grand" or "Great" in Russian. The towns of Opochka, Ostrov and Pskov are located on the banks of the Velikaya. The principal tributaries of the Velikaya are the Alolya (right), the Issa (left), the Sorot (right), the Sinyaya (left), the Utroya (left), the Kukhva (left), the Cheryokha (right), and the Pskova (right).

The source of the Velikaya is located in the Bezhanitsy Hills in the northwest of Novosokolnichesky District. The river flows south through a system of lakes to Lake Veryato, where it turns west. It accepts the Alolya from the right and gradually turns north, passing through the town of Opochka. Northwest of the urban-type settlement of Pushkinskiye Gory it turns west, accepts the Sinyaya from the left and turns north. In the city of Pskov the Velikaya accepts the Pskova from the right and turns northwest, forming a river delta as it enters Lake Peipus.

The drainage basin of the Velikaya comprises vast areas in the west and southwest of Pskov Oblast, as well as in the east of Latvia and in the north of the Vitebsk Region of Belarus.

The river has a significant historic importance. Pskov was founded in 903, and the Velikaya provided it with access to the sea, via Lake Peipus and the Narva River.

The Velikaya is navigable in its lower course of length 34 km.
