Abstract: Spectra of ${K}_{S}^{0}$ mesons and $\ensuremath{\Lambda}$ hyperons were measured in p + C interactions at 31 GeV/$c$ with the large acceptance NA61/SHINE spectrometer at the CERN SPS. The data were collected with an isotropic graphite target with a thickness of 4% of a nuclear interaction length. Interaction cross sections, charged pion spectra, and charged kaon spectra were previously measured using the same data set. Results on ${K}_{S}^{0}$ and $\ensuremath{\Lambda}$ production in p + C interactions serve as a reference for the understanding of the enhancement of strangeness production in nucleus-nucleus collisions. Moreover, they provide important input for the improvement of neutrino flux predictions for the T2K long baseline neutrino oscillation experiment in Japan. Inclusive production cross sections for ${K}_{S}^{0}$ and $\ensuremath{\Lambda}$ are presented as a function of laboratory momentum in intervals of the laboratory polar angle covering the range from 0 up to 240 mrad. The results are compared with predictions of several hadron production models. The ${K}_{S}^{0}$ mean multiplicity in production processes $\ensuremath{\langle}{n}_{{K}_{S}^{0}}\ensuremath{\rangle}$ and the inclusive cross section for ${K}_{S}^{0}$ production ${\ensuremath{\sigma}}_{{K}_{S}^{0}}$ were measured and amount to 0.127 $\ifmmode\pm\else\textpm\fi{}$ 0.005 (stat) $\ifmmode\pm\else\textpm\fi{}$ 0.022 (sys) and 29.0 $\ifmmode\pm\else\textpm\fi{}$ 1.6 (stat) $\ifmmode\pm\else\textpm\fi{}$ 5.0 (sys) mb, respectively.
