A measurement is presented of the associated production of a single top quark and a Z boson. The study uses data from proton-proton collisions at $$\sqrt{s} =$$ 13 TeV recorded by the CMS experiment, corresponding to an integrated luminosity of 35.9 fb$$^{-1}$$. Using final states with three leptons (electrons or muons), the tZq production cross section is measured to be $$\sigma$$(pp$$\to$$tZq$$\to$$Wb$$\ell^+\ell^-$$q) = $$123^{+33}_{-31}$$ (stat) $$^{+29}_{-23}$$ (syst) fb, where $$\ell$$ stands for electrons, muons, or $$\tau$$ leptons, with observed and expected significances of 3.7 and 3.1 standard deviations, respectively.
