The Pedja (Estonian: Pedja jõgi) is the fourth longest river in Estonia. Its source is near Simuna on the southern slopes of the Pandivere Upland. The river flows for 122 km through Lääne-Viru, Jõgeva and Tartu counties before joining the Emajõgi northeast of Lake Võrtsjärv. The last 4 km section of the river after confluence with Põltsamaa is known as the Pede.
