Gamma-ray transitions in the extremely neutron-deficient nucleus ${}^{106}\mathrm{Te}$ have been identified for the first time. The experiment utilized the ${}^{54}\mathrm{Fe}$(${}^{54}\mathrm{Fe}$,2n)${}^{106}\mathrm{Te}{}^{*}$ reaction, and the γ-ray transitions from excited states in ${}^{106}\mathrm{Te}$ were selected by use of the recoil-decay-tagging technique. The production cross section was estimated at 25 nb, a new limit for in-beam γ-ray spectroscopy. A ground-state band tentatively extending up to $I^{\pi }={10}^{+}$ is proposed. The systematics of low-lying yrast states in the Te isotopes is discussed within the context of vibrational excitations and residual nucleon-nucleon interactions.
