Delaware Route 202 (DE 202), also known as Concord Avenue, is a short state highway in Wilmington, Delaware. It runs from U.S. Route 13 Business (US 13 Bus., Market Street) north to a modified cloverleaf interchange with Interstate 95 (I-95) and US 202 at the northern city limits. North of the interchange, the route becomes US 202 northbound, also known as the Concord Pike. The road is two lanes and undivided for most of its length except for the part just south of the I-95 interchange, which is four lanes and divided. DE 202 was the southernmost part of US 202 until that highway was truncated to the I-95 interchange and later rerouted to follow I-95 through Wilmington and DE 141 down to US 13/US 40 near the New Castle Airport.

DE 202 begins at an intersection with US 13 Bus. (Market Street) in the city of Wilmington, heading north on two-lane undivided Concord Avenue. The road passes urban areas of homes and businesses in the northern part of the city. Concord Avenue crosses several streets including Washington Street and Baynard Boulevard. At the intersection with the latter, the road becomes four lanes and becomes a divided highway at the Franklin Street intersection. After passing under CSX’s Philadelphia Subdivision, DE 202 reaches an interchange with I-95 and US 202, where DE 202 ends and the road continues north as part of US 202 (Concord Pike).

DE 202 has an annual average daily traffic count ranging from a high of 25,601 vehicles at the north end of Wilmington to a low of 8,387 vehicles at the Baynard Boulevard intersection. None of DE 202 is part of the National Highway System.

When the U.S. Highway System was created in 1926, what is now DE 202 was designated as the southernmost part of US 122, a U.S. highway that ran from US 13 in Wilmington north to New Jersey. By the mid-1930s, the US 122 designation was replaced with US 202, and the route was shifted to head southwest from Concord Avenue and continue into downtown Wilmington on Washington Boulevard. By 1959, US 202 was moved onto a one-way pair through downtown Wilmington, with the southbound direction splitting from Concord Avenue to follow Baynard Boulevard to Washington Street and the northbound direction turning onto Concord Avenue at Market Street (US 13). In 1971, US 202 was aligned to head south on Concord Avenue to end at US 13 Bus. The portion of US 202 south of the I-95 interchange was designated DE 202 by 1981 when US 202 was cut back to the I-95 interchange.

The entire route is in Wilmington, New Castle County.
