Measurements of \(K_S^0\) meson production via its \(\pi^{+} \pi^{-}\) decay mode in inelastic \(\textit{p+p}\) interactions at incident projectile momenta of 31, 40 and 80 GeV/\(c\) (\(\sqrt{s_{NN}}=7.7, 8.8\) and \(12.3\) GeV, respectively) are presented. The data were recorded by the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron. Double-differential distributions were obtained in transverse momentum and rapidity. The mean multiplicities of \(K_S^0\) mesons were determined to be \((5.95 \pm 0.19 (stat) \pm 0.22 (sys)) \times 10^{-2}\) at 31 GeV/\(c\), \((7.61 \pm 0.13 (stat) \pm 0.31 (sys)) \times 10^{-2}\) at 40 GeV/\(c\) and \((11.58 \pm 0.12 (stat) \pm 0.37 (sys)) \times 10^{-2}\) at 80 GeV/\(c\). The results on \(K^{0}_{S}\) production are compared with model calculations (Epos1.99, SMASH 2.0 and PHSD) as well as with published data from other experiments.
