Widener University Delaware Law School (Delaware Law School and formerly Widener University School of Law) is a private law school in Wilmington, Delaware. It is one of two separate ABA-accredited law schools of Widener University. Widener University Law School was founded in 1971 as the Delaware Law School and became affiliated with Widener in 1975. In 1989, it was known as Widener University School of Law when it was combined with the campus in Harrisburg, Pennsylvania. In 2015, the two campuses separated, with the Harrisburg one renamed to Widener University Commonwealth Law School.

Founded in 1971 as The Delaware Law School, the institution became affiliated with then Widener College, later becoming Widener University in 1975 and graduated its first class of 267 in August of that year. The school's name was officially changed to Widener University School of Law in 1989 when the Harrisburg campus was added. On July 1, 2015, the two campuses were separated into two distinct law schools that operate independently of each other, but remain part of the university. Each law school has its own dean, faculty, students, and curriculum.

Located in Wilmington, Delaware Law School's 40-acre campus is home to 686 students.

Widener's legal education program included legal clinics that specialize in environmental law, criminal defense, and civil law, which includes family law, and legal assistance on veteran benefits cases. Another opportunity provided to its students is the Taishoff Advocacy, Technology and Public Service Institute, which offers an eight-day training program that teaches students how to conduct themselves properly in a courtroom trial.

In addition to legal clinics and the Taishoff Advocacy, Technology and Public Service Institute, Widener offers certification in specialized fields of study.

The campus offers a variety of pro-bono work or community outreach opportunities through the Public Interest Resource Center. Students also have the opportunity participate in extra and co-curricular activities such as Moot court, Moe Levine Trial Advocacy Honor Society, and two law reviews: the Delaware Journal of Corporate Law and the Widener Law Review.
