Wyoming Highway 30 is a Wyoming State Road known locally as Otto Road located in southwestern Big Horn County and serves the town of Burlington and unincorporated community of Otto.

Wyoming Highway 30 is mostly an east-west highway, but travels north-south at its west end. WYO 30 has its west end at US 14/US 16/US 20 in the unincorporated community of Emblem, just six-tenths of a mile west of Wyoming Highway 32's southern terminus. WYO 30 serves several small communities and ranches to the west of Worland and is an alternate to US 16/US 20 between Emblem and Basin. WYO 30 heads south reaching the town of Burlington at 3.79 miles. After leaving the town of Burlington, Highway 30 turns east to head toward Otto, reaching that community by 10.30 miles. WYO 30 continues east, to Basin intersecting Wyoming Highway 36 at its southern terminus. Shortly after, WYO 30 comes to its eastern end at US 16/US 20/WYO 789 (4th Street). Mileposts increase from east to west along Wyoming 30.

The entire route is in Big Horn County.
