Delaware Route 92 (DE 92) is a 8.83-mile (14.21 km) long road in northern New Castle County, Delaware that runs a short distance to the south of the Pennsylvania/Delaware state line for most of its length. The route runs from DE 100 near Montchanin east to U.S. Route 13 (US 13) in Claymont. The road is a two-lane rural road between the western terminus and US 202, passing through Brandywine Creek State Park. East of US 202, DE 92 is a four-lane divided highway called Naamans Road that passes through suburban areas to the north of Wilmington, interchanging with Interstate 95 (I-95) in Claymont. DE 92 was first built as a state highway east of US 202 during the 1920s and 1930s. By 1968, the route was designated onto its current alignment. In the 1990s, DE 92 east of US 202 was widened into a divided highway.

DE 92 begins at the intersection with DE 100 and Adams Dam Road near Montchanin. The route heads northeast on a two-lane undivided road called Thompson Bridge Road, passing through farmland to the north of Brandywine Creek State Park. The road continues into forested areas of the state park, crossing the Brandywine Creek. After the state park, DE 92 heads into agricultural areas, continuing northeast along Ramsey Road before curving to the north. The route turns east onto Beaver Valley Road, widening into a four-lane divided highway as it passes between business parks to the north and farmland to the south, intersecting US 202.

Past the US 202 intersection, DE 92 becomes Naamans Road and passes between the Brandywine Town Center shopping center to the north and inhabited and commercial areas to the south, intersecting Shipley Road. Past the Brandywine Town Center, the route heads through suburban residential neighborhoods in Brandywine Hundred and intersects Ebright Road, which goes north to the highest point in Delaware (Ebright Azimuth) and into Pennsylvania. The road passes more homes and comes to an intersection with DE 261 in a commercial area. DE 92 heads near more residential areas and comes to a junction with the northern terminus of DE 3. From here, the road runs through more suburban development, passing over CSX's Philadelphia Subdivision and turning to the east-southeast. The route heads into commercial areas in Claymont and comes to an interchange with I-95 at the northern terminus of I-495. After the I-95 interchange, DE 92 passes the Tri-State Mall and comes to an intersection with the southern terminus of DE 491. Past this intersection, the route turns southeast, passing more businesses and crossing a railroad spur before ending at US 13.

DE 92 has an annual average daily traffic count ranging from a high of 28,720 vehicles at the Shipley Road intersection to a low of 8,065 vehicles at the Creek Road intersection. None of DE 92 is part of the National Highway System.

By 1920, what is now DE 92 originally existed as a county road, with the portion east of Foulk Road proposed to become a state highway. The state highway between Foulk Road and Philadelphia Pike was completed by 1924. By 1931, the portion of road between Grubb Road and Foulk Road was upgraded to a state highway. When Delaware first numbered its state highways by 1936, what is now DE 92 remained unnumbered, with the state highway portion extended west to Concord Pike. By 1968, DE 92 was designated onto its current alignment between DE 100 and US 13, with the easternmost portion replacing what had been designated a part of US 13 Bypass. DE 92 was widened into a divided highway by 1997 between US 202 and DE 261 and between DE 3 and DE 491. By 1999, the road was upgraded to a divided highway between DE 261 and DE 3.

The entire route is in New Castle County.
