The Yelm–Rainier–Tenino Trail, formerly the Yelm–Tenino Trail, is a rail trail located in Thurston County, Washington, United States. The trail, acquired by the county in 1993, is a 14.5-mile (23.3 km) long cycling and walking trail has been constructed along the route of a former Burlington Northern Railroad line. Originally this section of railroad was named "The Prairie Line," but in 1986 the rail line from Yelm to Tenino was abandoned.
The trail runs parallel to State Route 507 and intersects with the southern end of the Chehalis Western Trail. Trailheads are located at the trail termini in Yelm and Tenino, with additional parking lots and entry points along the trail. Rainier straddles the trail approximately 8.5-mile (13.7 km) east of Tenino. The trail is mainly flat, with only a change of approximately 320 feet (98 m) over the course of the trail.
The trail was renamed in late 2021. Previously the "Yelm–Tenino Trail", the name now incorporates the city of Rainier, which maintains a portion of the trail that bisects the area and the city's limits.
