The Triangle Universities Nuclear Laboratory, abbreviated as TUNL (pronounced as "tunnel"), is a tripartite research consortium operated by Duke University, the University of North Carolina at Chapel Hill, and North Carolina State University. The laboratory is located on the West Campus of Duke University in Durham, North Carolina. TUNL now draws researchers from from several other universities in addition to members from the founding universities.

Research at TUNL is focused on nuclear physics, including studies on Nuclear structure, Nuclear astrophysics, and Hadron structure. TUNL also conducts applied research, investigating the applications of nuclear physics to topics such as National security, Public health, and Plant physiology.

Equipment used at TUNL includes two Van de Graaff accelerators: an FN Tandem accelerator capable of a terminal voltage of 10 megavolts (the centerpiece of the lab), and a 1 megavolt single-ended JN accelerator used for nuclear astrophysics studies. Experiments involving the interaction of electromagnetic radiation with nuclear matter are frequently conducted at a neighboring facility, the Duke Free Electron Laser Laboratory; along with collaborative efforts, TUNL is increasingly involved in off-site experiments, such as proposed research activities at the Kimballton mine in Virginia.
