The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector that will study reactor antineutrinos emitted from two nuclear power plants in the south of China at a baseline of about 53 km. Thanks to its two photon detection systems (17612 20-inch PMTs and 25600 3-inch PMTs), JUNO will achieve an unprecedented 3\% energy resolution at 1 MeV along with an energy scale calibration uncertainty of 1\%. Such powerful detector performances will allow to resolve, for the first time, the interference pattern between the solar and atmospheric oscillation modes. Therefore, the primary physics goals of JUNO include the determination of the neutrino mass ordering at a 3-sigma confidence level and the measurement of three neutrino oscillation parameters, $\sin^{2}\theta_{12}$, $\Delta$m$^{2}_{21}$ and $\Delta$m$^{2}_{32}$, with sub-percent precision. This talk will cover the oscillation physics potential of JUNO, also showing the impact of JUNO future results within the global neutrino framework.
