Wyoming Highway 34 ('WYO 34), also known as Laramie-Wheatland Road, is a 52.38-mile (84.30 km) state highway in Albany and Platte counties in Wyoming, United States, that connects U.S. Routes 30 / 287 (US 30 / US 287) south-southeast of Bosler with Interstate 25 / U.S. Route 87 (I‑25 / US 87) south of Wheatland.

WYO 34 begins at a T intersection with US 30 / US 287 about 1.8 miles (2.9 km) south-southeast of Bosler and just south of the Laramie River. From its western terminus it heads northeasterly toward Wheatland by the way of Morton Pass. Nearing its eastern end, WYO 34 connects with the southern end of Wyoming Highway 312 in Ferguson Corner, which is the former routing of WYO 34 into Wheatland. WYO 34 reaches its eastern terminus at a diamond interchange with I‑25 / US 87 (I‑25 Exit 73) just south of Wheatland.^[2]

WYO 34 follows State Control Route S-109 for its entire length.^{[citation needed]}

Between 1926 and November 1949, WYO 34 was designated as Wyoming Highway 26.^{[citation needed]} After U.S. Route 26 (US 26) was extended west across Wyoming to Wheatland (where it ended at US 87) and US 26 was officially designated, WYO 26 was renumbered WYO 34 to avoid confusion.^[1]
