Delaware Route 404 (DE 404) is a major state highway in Sussex County, Delaware that spans the east-west width of the state. DE 404's western terminus is at the Maryland border northwest of Bridgeville, where the road continues into that state as Maryland Route 404 (MD 404), and its eastern terminus is at the Five Points intersection with U.S. Route 9 (US 9), DE 1, and US 9 Business (US 9 Bus.) in Nassau. The route passes through rural areas as well as the towns of Bridgeville and Georgetown. DE 404 runs concurrent with DE 18 from east of Bridgeville to Georgetown and with US 9 from Georgetown to Five Points. DE 404 has a business route, DE 404 Bus., that passes through Bridgeville and a truck route, DE 404 Truck, that bypasses Georgetown. DE 404, along with MD 404, serves as a major route connecting the Chesapeake Bay Bridge and the Baltimore–Washington Metropolitan Area with the Delaware Beaches.

DE 404 was first designated by 1936 to run from the Maryland border to DE 18 southeast of Bridgeville. The route was extended east to Five Points by 1987. By 1999, DE 404 was realigned to bypass Bridgeville, with DE 404 Bus. designated on the former route through the town. The new alignment of DE 404 around Bridgeville replaced DE 404 Alternate (DE 404 Alt.), which was designated by 1990.
