Lorentz invariance (LI) underlies both the Standard Model of particle physics and General Relativ- ity, and it represents our understanding of the nature of spacetime. It is therefore of fundamental interest to test its validity in every accessible regime as this would allow us to probe the mi- croscopic structure of space-time and to constrain quantum gravity models. Lorentz Invariance Violation (LIV) would modify the observed energy and zenith angle distributions of atmospheric neutrinos that can be detected by neutrino telescopes such as KM3NeT. KM3NeT/ORCA115 is a next-generation neutrino telescope under construction in the Mediterranean sea, and is optimised for atmospheric neutrino oscillations studies. In this contribution, the sensitivity of ORCA115 to the presence of LIV is presented.
