The Malad River is a tributary of the Snake River in Idaho in the United States. It is formed by the confluence of the Big Wood River and the Little Wood River near Gooding. From there the river flows south and west for 12.0 miles (19.3 km)[3] to join the Snake River near Hagerman.[2]

The river flows through Malad Gorge State Park, where it tumbles down a stairstep waterfall. The Malad Gorge is 250 feet (76 m) deep and 2.5 miles (4.0 km) long.

The river's flow is affected by numerous reservoirs and irrigation works on its tributaries. The Malad River itself is largely diverted into a power flume that enters the Snake below the mouth of the Malad, via a powerhouse. Below the diversion the Malad River is replenished by numerous springs, yet the average flow above the diversion is higher than at the river's mouth.[4]

The Malad River is part of the Columbia River basin, being a tributary of the Snake River, which is a tributary to the Columbia River.[5]

The name of the river stems from French malade, via Rivière aux Malades ('river of the sick'), presumably as a reference to some illness suffered by early French-Canadian trappers who investigated the area.[6]
