Isluga River is a river in Chile and Bolivia, and is also known as Sitani or Arabilla. It starts at the confluence of the rivers Chaguane and Huinchuta and flows for 54 kilometres (34 mi) before reaching the Laguna Mucalliri of the Salar de Coipasa. It receives water from the volcanoes Isluga, Cabaray and Quimsachata as well as the Sierra Uscana.

The watershed of the river lies mainly in Chile and has a dry climate, resulting in a small river discharge of about 0.4–0.5 cubic metres per second (14–18 cu ft/s). There are a number of towns and hamlets in the catchment, as well as wetlands with a number of animal and plant species.
