State Route 705 (SR 705) is a short state highway in Douglas County, Nevada. The route follows a portion of Clear Creek Road just south of Carson City. The route was once part of the Lincoln Highway, forming a major travel link between Carson City and Lake Tahoe.

State Route 705 begins in Douglas County at the Carson City/Douglas County line southwest Carson City on Clear Creek Road (shown on some maps as "Old Clear Creek Road"), just north of Clear Creek. The state-maintained highway follows Clear Creek Road eastward along the course of Clear Creek for nearly one mile. SR 705 ends at the Douglas County/Carson City line, but the road continues eastward to an intersection with U.S. Route 395 (US 395). State Route 705 is currently not directly connected to the remainder of Nevada's state highway system.

Trails connecting Lake Tahoe with the Comstock Lode mining region near Carson City had been established in the mid-1800s, with the first wagon road route through Kings Canyon to the north having been constructed by November 1863. This route was eventually selected to become part of the Lincoln Highway and, later, a branch of State Route 3.

The advent of the automobile greatly changed this region of Nevada. From 1927 to 1928, aided by both state and forest highway funding, a graded two-lane road was constructed along the corridor of Clear Creek to connect Carson City to Spooner Summit, just east of Glenbrook on the eastern shore of Lake Tahoe. The Clear Creek Road replaced the former Kings Canyon route as the major road to Lake Tahoe in 1928, and was subsequently selected as a later realignment of the Lincoln Highway. Clear Creek Road later became part of U.S. Route 50, but was bypassed in the 1950s by the current four-lane alignment located a short distance to the north.

Clear Creek Road remained largely unchanged since it was established. The Nevada Department of Transportation initially designated State Route 705, from the current western terminus east to a Bureau of Indian Affairs water diversion box in Carson City, by January 11, 2000. By the beginning of 2006, the short portion with Carson City had been removed from state maintenance, resulting in the current highway segment in Douglas County.

The entire route is in Douglas County.
