KM3NeT/ORCA, currently under construction in the Mediterranean Sea, is a next-generation neutrino telescope optimised for atmospheric neutrino oscillations studies. To date, 10 out of the expected 115 detection units are taking data. This contributions shows the latest results from ORCA in testing the light sterile neutrino hypothesis in a 3+1 model. The large neutrino sample that will be collected by ORCA over a broad range of baselines and energies will probe active-sterile mixing with mass squared differences ∆m41^2 between 10^-5 and 10 eV^2, contributing to testing the eV-mass sterile neutrino hypothesis as the origin of short baseline anomalies, as well as probing smaller sterile neutrino masses not yet constrained by cosmology or any other current experiment.
