The Ese (French: Ese or Rivière d'Ese) is a river in the department of Corse-du-Sud, Corsica, France. It is a tributary of the Prunelli river, which it joins in the Lac de Tolla.

The Ese is 21.03 kilometres (13.07 mi) long. It crosses the communes of Bastelica, Ciamannacce, Frasseto, Guitera-les-Bains, Tasso and Tolla. It rises in the commune of Ciamannacce to the north of the 1,950 metres (6,400 ft) Monte Giovanni. It passes a ski resort, the Val d'Ese, in its upper reaches. It flows in a generally southwest direction, then turns west and joins the Prunelli at the head of Lac de Tolla.

The D27a leads from Bastelica for 15 kilometres (9.3 mi) to the Ese plateau at 1,622 metres (5,322 ft). In winter there is a downhill and cross-country ski resort here. If there is no snow, visitors can hike in the Pozzines. Lower down, the Ese is crossed by the magnificent Zipitoli Genoese bridge near its confluence with the Prunelli. The bridge is near the point where the D27 crosses the Ese, and can be reached by a short walk.

The Lac de Tolla is formed by a dam (Barrage de Tolla) on the Prunelli river. The Ruisseau d'Agnone and the Ese River also empty into the lake. It is in the commune of Tolla just south of the village of Tolla. Lake Tolla is at an altitude of 550 metres (1,800 ft).
