Fallon National Wildlife Refuge, National Wildlife Refuge in northern Nevada.

Fallon National Wildlife Refuge covers over 15,000 acres of playa and wetland habitat in the Carson Sink, at the terminus of the Carson River in the Lahontan Valley. The refuge lies at 1,181 metres above sea level, and the surrounding terrain is mostly flat, with Topog Peak rising 16.4 km to the south.

The refuge was established in 1931 to provide shelter for migratory birds traveling the Pacific Flyway route. Its creation was part of a broader effort to protect critical stopover habitats across the western United States.

The refuge lies in the Carson Sink, the terminus of the Carson River in the Lahontan Valley. In years when high flows carry the river far enough, its wetlands draw migratory shorebirds and waterfowl; in most years diversions leave too little water to reach the refuge lands at all.

The refuge is open every day around the clock, but it has no facilities, so bring your own water and supplies. Roads are primitive and passable only in dry weather; rain can leave them impassable. The entrance lies at the end of a dirt track off US Route 50 near Fallon, in Churchill County.

The refuge lies at the terminus of the Carson River in the Carson Sink, and in most years water diversions upstream mean the river does not reach the refuge at all. When high flows do arrive, the playa and wetlands become important for migratory shorebirds and waterfowl.
