  <dc:description>The first observation of the electroweak (EW) production of a $Z$ boson, a photon, and two forward jets ($Z\gamma \mathrm{jj}$) in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. A data set corresponding to an integrated luminosity of $137\text{}\text{}{\mathrm{fb}}^{-1}$, collected by the CMS experiment at the LHC in 2016–2018 is used. The measured fiducial cross section for EW $Z\gamma \mathrm{jj}$ is ${\sigma }_{\mathrm{EW}}=5.21±0.52\left(\mathrm{stat}\right)±\phantom{\rule{0ex}{0ex}}0.56\left(\mathrm{syst}\right)\text{}\text{}\mathrm{fb}=5.21±0.76\text{}\text{}\mathrm{fb}$. Single-differential cross sections in photon, leading lepton, and leading jet transverse momenta, and double-differential cross sections in ${m}_{\mathrm{jj}}$ and $|\Delta {\eta }_{\mathrm{jj}}|$ are also measured. Exclusion limits on anomalous quartic gauge couplings are derived at 95% confidence level in terms of the effective field theory operators ${M}_{0}$ to ${M}_{5}$, ${M}_{7}$, ${T}_{0}$ to ${T}_{2}$, and ${T}_{5}$ to ${T}_{9}$.</dc:description>
