We report the first detection of coherent elastic neutrino-nucleus scattering (CEvNS) on natural germanium, measured at the Spallation Neutron Source at Oak Ridge National Laboratory. The Ge-Mini detector of the COHERENT collaboration employs large-mass, low-noise, high-purity germanium spectrometers, enabling excellent energy resolution, and an analysis threshold of 1.5 keV electron-equivalent ionization energy. We observe an on-beam excess of 20.6_{-6.3}^{+7.1} counts with a total exposure of 10.22 GWhkg, and we reject the no-CEvNS hypothesis with 3.9σ significance. The result agrees with the predicted standard model of particle physics signal rate within 2σ.
