The New Castle County Chamber of Commerce is a regional organization in the civic and social sector that serves businesses across New Castle County, based in Wilmington, Delaware. Its origins date back to 1922, when it was established as the Newark Chamber of Commerce and later evolved through the 1960s, becoming the Greater Newark Chamber of Commerce before adopting its current name. The chamber conducts government affairs work, organizes events, provides support for emerging businesses, offers health and insurance benefits to members, and administers a broad slate of programs for firms of all sizes.

There have been leadership changes in recent years, including the appointment of Yvonne Deadwyler as interim president in 2024, with the role formalized in March. In 2026, the chamber announced plans for its 104th Annual Dinner, scheduled for May 4 at the Chase Center on the Riverfront, with a keynote speaker and award recipients named. Also in 2026, Comcast partnered with the chamber to celebrate the opening of a new Xfinity Store in Wilmington via a ribbon-cutting ceremony.
