Washington State Route 410, formerly U.S. Highway 410, is a 107.53 mile (173.05 km) highway in southwestern Washington state, USA. It runs from SR 167 in Sumner east via Mt. Rainier National Park to US 12 west of Yakima.

The westernmost piece is a freeway bypassing downtown Sumner. From the end of the freeway, SR 410 heads east via Enumclaw and the northeast part of Mt. Rainier National Park to end at US 12.

As US 410, the highway continued west into Tacoma via SR 167 , and then ran southwest on US 99 (now I-5) to Olympia and west on US 101, SR 8 and US 12, ending at US 101 in Aberdeen. It also continued east via what is now US 12 to Lewiston, Idaho.

In late 1967, US 12 was extended west from Lewiston along most of US 410, bypassing Mt. Rainier National Park and Tacoma and Olympia to the south. The part from I-5 in Tacoma east became SR 410; the short section out of Tacoma until Sumner became SR 167 in 1973. Because of this 1973 truncation, SR 410 begins at milepost 8.84 (and ends at milepost 116.37).
