The Vispa is a river in the canton of Valais, located in the Visp area. It is essentially composed of two large branches: the Matter Vispa and the Saaser Vispa, converging at Stalden, then forming the Vispa proper, flowing for less than 10 kilometres (6.2 mi) before converging with the Rhône at Visp.
The Vispa is a left and major affluent of the Rhône, before it enters Lake Geneva.
