Delaware Route 273 (DE 273) is a state highway in New Castle County, Delaware. The route runs from Maryland Route 273 (MD 273) at the Maryland border near Newark east to DE 9 and DE 141 in New Castle. The route heads through suburban areas between Newark and New Castle as a multilane road, passing through Ogletown and Christiana. DE 273 intersects DE 896 in downtown Newark; DE 2/DE 72 on the eastern edge of Newark; DE 4 in Ogletown; Interstate 95 (I-95), DE 7, and DE 1 in Christiana; DE 37 in Pleasantville; and DE 58 and U.S. Route 13 (US 13)/US 40 in Hares Corner.

What is now DE 273 was originally built as a state highway in the 1920s and 1930s, with the portion east of Hares Corner becoming a part of US 40, which had crossed the Delaware River on a ferry between New Castle and Pennsville, New Jersey. DE 273 was designated by 1936 to run from the Maryland border near Newark east to Hares Corner. In the 1950s, the route was extended east to New Castle when US 40 was realigned to the Delaware Memorial Bridge. DE 273 was moved onto new alignments around Christiana in the 1980s and through Ogletown in the 1990s.
