contents	Atmospheric neutrinos provide a unique avenue to study neutrino interactions in matter. In this work, the prospects of constraining non-standard neutrino interactions with atmospheric neutrino oscillations are investigated for the proposed ESSnuSB far detector. By analyzing atmospheric neutrino samples equivalent to 5.4 Mt$\cdot$year exposure, it is found that ESSnuSB could be able to set the upper bounds $\|ε_{eμ}^m\| < 0.053, \|ε_{eτ}^m\| < 0.057, \|ε_{μτ}^m\| < 0.021, ε_{ee}^m - ε_{μμ}^m < 0.075$ and $\|ε_{ττ}^m - ε_{μμ}^m\| < 0.031$ at $90\%$ CL, when the results are minimized for $ϕ_{eμ}^m, ϕ_{eτ}^m$ and $ϕ_{μτ}^m$ and normal ordering is assumed for neutrino masses. It is also shown that the presence of non-standard interactions could affect the sensitivities to neutrino mass ordering and $θ_{23}^{}$ octant in comparison to the standard interaction scheme. The results of this work highlight the complementarity between atmospheric and accelerator neutrino programs in ESSnuSB.
