  The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton
multi-purpose liquid scintillator detector currently being built in a dedicated
underground laboratory in Jiangmen (PR China). Data-taking is expected to start
in 2023. JUNO's main physics goal is the determination of the neutrino mass
ordering using electron anti-neutrinos from two nuclear power plants at a
baseline of about 53 km. JUNO aims for an unprecedented energy resolution of 3
$\%$ at 1 MeV for the central detector, which will allow determining the mass
ordering with 3 $\sigma$ significance within six years of operation.
Furthermore, measurements in neutrino physics and astrophysics, such as
estimating the solar oscillation parameters and the atmospheric mass splitting
with an accuracy of 0.5 $\%$ or better, will be performed. In these
proceedings, JUNO's design, the status of its construction, and its physics
potential, will be presented alongside a short excursion into its rich R$\&$D
program.
