### Description

The neutrino oscillation is the first observed phenomenon beyond the standard model, which can be interpreted in the framework of three neutrino mixings. It is governed by three mixing angles, two mass-squared differences, and one Dirac CP violation phase. The neutrino mass ordering, CP violation phase and the octant of $\theta_{23}$ remain unknown and could be measured by next-generation neutrino oscillation experiments. Jiangmen Underground Neutrino Observatory (JUNO) consists of a 20 kiloton liquid scintillator detector, which primarily aims to determine the neutrino mass orderings by measuring the reactor antineutrino oscillation pattern at a baseline of about $53$ km. A $3\sim4\sigma$ significance to resolve mass orderings could be reached after 6 years of operation benefiting from its unprecedented 3\% energy resolution at 1 MeV. Besides, JUNO is able to perform measurements at an accuracy of better than 1\% to oscillation parameters $\sin^{2}\theta_{12}, \Delta m^{2}_{21}$ and $\Delta m^{2}_{32}$. In this talk, neutrino oscillation studies in JUNO will be reviewed.
