Relationship between antiferromagnetic order with Néel temperature of 35 K and charge-density-wave (CDW) order below 320 K of UPt$_{2}$Si$_{2}$ has been investigated by resonant X-ray scattering measurements. We have found that a resonant scattering signal develops below the Néel temperature at the $ M_{\rm 4}$ absorption edge of uranium with a propagation vector of the CDW order $q_{\rm CDW} \sim$ (0.42, 0, 0). The experimental results reveal that the magnetic structure of UPt$_{2}$Si$_{2}$ is modulated by the CDW ordering.
