In this study we use MUSE Integral Field Spectroscopy (IFS), along with multi-line diagnostics, for the optical identification of Supernova Remnants (SNRs) in the galaxy NGC 7793. We find in total 238 SNR candidates, 225 of them new identifications, increasing significantly the number of known SNRs in this galaxy. The velocity dispersion of the candidate SNRs was calculated, giving a mean value of 27 km\, s^ -1. We construct the H, S II, O III, and S II - H luminosity functions, and for the first time, the N II, N II - H, N II - S II, O III - S II, and O III - N II luminosity functions of the candidate SNRs. Shock models, along with the observed multi-line information were used, in order to estimate shock velocities. The 65% of the SNRs present velocities 0. 4 and S II/H < 0. 4 is observed.
