U.S. Route 410 (US 410) was a U.S. Highway in Washington and Idaho that existed from 1926 to 1967. It ran 469 miles (755 km) from US 101 in Aberdeen, Washington, to US 95 in Lewiston, Idaho, passing through the cities of Olympia, Tacoma, Yakima, the Tri-Cities, and Walla Walla.

The highway had concurrencies with SR 8, US 99, and US 395. Even though the number indicates that US 410 was a spur of US 10, US 410 never connected with US 10, which is the same case with US 830 and US 30, although like the latter pair, they ran parallel in close proximity. When US 12 was extended into Washington in 1967, US 410 was decommissioned.
