State Route 6 (SR 6) is a 51.37-mile (82.67 km) long state highway in Pacific and Lewis counties in the U.S. state of Washington. The highway, which extends from U.S. Route 101 (US 101) in Raymond east to Interstate 5 (I-5), co-signed with US 12 in Chehalis. Major communities located on the highway include Raymond, Pe Ell, Adna and Chehalis. The first state highway that used the current route of SR 6 was State Road 19, established in 1913. State Road 19 became State Road 12 in 1923, which became Primary State Highway 12 (PSH 12) in 1937. In 1964, PSH 12 became SR 6 and since, three minor construction projects have been arranged, only two have been completed.

State Route 6 (SR 6) begins at an intersection with U.S. Route 101 (US 101) in Downtown Raymond as Henkle Street. Paralleling the basic route of the Willapa River, the highway turns southeast to leave Raymond and become unnamed. Continuing past Menlo, the roadway realigns directly south to Holcomb before curving back eastward to Lebam and Frances to exit Pacific County and enter Lewis County. Once in Lewis County, the Willapa River ends in the Willapa Hills, while the road turns northeast and later east into Pe Ell. In Pe Ell, SR 6 is named 4th Avenue and crosses the Chehalis River, while the highway is once again unnamed at the Main Street intersection. At the Main Street intersection, the roadway is realigned north to Doty and east to Dryad and Rainbow Falls State Park, where the road goes south and curves northeast to Adna. In Adna, SR 6 starts to parallel a railroad owned by the Port of Chehalis and operated by the Puget Sound and Pacific Railroad and then the highway crosses the Chehalis River again. The road leaves the community and Littell to intersects Co Road, which had been SR 603 before 1991. After crossing the Chehalis River for the final time into Chehalis, the roadway ends at a diamond interchange with Interstate 5 (I-5), co-signed as US 12. The busiest segment of SR 6 in 2007 was the I-5 / US 12 interchange in Chehalis, with an estimated daily average of 13,000 motorists. In 1970, the busiest segment was the US 101 intersection in Raymond, with an estimated daily average of 4,800 motorists.
