Wyoming Highway 320 (WYO 320) is a 12.33-mile-long (19.84 km) north–south state highway in central Platte County, Wyoming that connects Interstate 25 Business (I-25 Bus.) and U.S. Route 87 Business (US 87 Bus.) in Wheatland to US 26 in Dwyer, and was once part of the Yellowstone Highway.

Wyoming Highway 320 begins its south end at I-25 Business/US 87 Business (9th Street/Swanson Road) in Wheatland. From here WYO 320 heads north, intersecting East Laramie River Road at 4.6 miles (7.4 km), which can take you west to I-25 (exit 84). Highway 320 continues north till its end at US 26 in Dwyer

Wyoming Highway 320 was originally designated in Fremont County along what is now Wyoming Highway 789 between Lander and Shoshoni between 1939 and 1950. It was originally US 320 between 1926 and 1938 but in 1939 was recommissioned as Wyoming Highway 320. In 1940, when US 287 and Wyoming Highway 287 were rerouted, Wyoming 320 was extended southwest to Lander. WYO 320 maintained this until 1950, when US 26 was commissioned. WYO 320 lasted until 1954, when Wyoming Highway 789 was commissioned, thereby replacing it.
