State Route 400 (SR 400) is a state highway in central Pershing County, Nevada. It connects the rural town of Unionville to Mill City. The route originally extended further south under its prior designation as State Route 50.
The route starts at the beginning of pavement on Unionville Road, about 3 miles (4.8 km) east of the rural townsite of Unionville in Buena Vista Valley at Kyle Hot Springs Road. From there, SR 400 heads northward over Buena Vista Creek as it heads northward towards Coyote Ranch. The route parallels the Humboldt Range on its trek northward through the desert. The highway crosses over Star Creek and passes through the Dun Glen Flat as it heads into Mill City. State Route 400 comes to an end at the Mill City Interchange on Interstate 80 and U.S. Route 95.
The route's history begins as far back as 1933, when it appeared on official Nevada maps as a county road, diverging from old U.S. Route 40 beginning in Mill City and heading southerly past the current terminus through the town of Rochester, then westerly to reconnect to US 40. By 1935, the county road had been designated State Route 50 by the state. The route, as it existed in 1936, was an unpaved road approximately 42 miles (68 km) long. By 1941, SR 50 had been rerouted slightly to bypass Rochester to the north, connecting west to Oreana more directly and shaving 3 miles (4.8 km) miles of the route's length. The northern end of the route, composing the current limits of the highway, was paved by 1959.
