State Route 524 (SR 524) is a suburban state highway in the U.S. state of Washington, located entirely within Snohomish County. It begins at SR 104 in Edmonds and travels east past SR 99, Interstate 5 (I-5), under I-405, past SR 527 and SR 9 to end at SR 522 in Maltby. The road also has two spur routes, one connecting to SR 104 in Edmonds and another connecting to I-5 in Lynnwood.
First appearing on a map in 1895, the highway was designated as part of Secondary State Highway 1W (SSH 1W) in 1957 during an extension from Edmonds to Lynnwood. SSH 1W was extended further to SSH 2J (present-day SR 527) in 1959 before becoming SR 524 in 1964. A final extension east to SR 522 was completed in 1991.
