State Route 175 (SR 175) is a primary state highway in the U.S. state of Virginia. Known as Chincoteague Road, the state highway runs 10.49 miles (16.88 km) from U.S. Route 13 (US 13) at Nash Corner east to Main Street in Chincoteague. SR 175 passes through the northeastern corner of Accomack County, providing the primary access to NASA's Wallops Flight Facility and both Chincoteague Island and the Virginia portion of Assateague Island. The route travels between the mainland and Chincoteague Island along the John B. Whealton Memorial Causeway.

In 1928, SR 520 was designated to run from US 13 in Oak Hall east toward Chincoteague Island, being extended onto the island in 1930. The route was extended south along US 13 and west to a railroad crossing west of Oak Hall in 1930. SR 520 became SR 175 in the 1933 Virginia state highway renumbering. SR 175 was extended south on Main Street in Chincoteague a year later and east on Beebe Road the following year, at which time a spur route known as SR 175Y was designated onto the northern portion of Main Street. The western terminus was moved to its current location in 1947, with the section west of US 13 becoming part of SR 703. SR 175 was routed to bypass Wallops Station to the south in 1954. In 1992, the section of SR 175 in Chincoteague, along with all of SR 175Y, was transferred to the secondary system. SR 175 was rerouted to bypass Marsh Island and a swing bridge over Chincoteague Channel with a new bascule bridge further north in 2010, tying into Main Street at Maddox Boulevard. The former swing bridge was demolished and a spur off the new bridge was built to serve Marsh Island.
