The Deep Underground Neutrino Experiment (DUNE) collaboration will provide a rich science program with the focus on accelerator-based long-baseline neutrino studies along with nucleon decay and topics in neutrino astrophysics. One of the most important goals of the experiment is to determine the neutrino mass ordering and the measurement of the CP violating phase. It will consist of a modular 40-kt (fiducial) mass liquid argon time-projection chamber (LArTPC) far detector, located deep underground at the Sanford Underground Research Facility in South Dakota, and a high-resolution and high-precision near detector. This configuration will have a 1300-km baseline in a multi-megawatt wide-band neutrino beam provided by the Long-Baseline Neutrino Facility (LBNF). In this presentation, we will discuss the physics motivations and the main experimental features of the DUNE project.
