The ground-state Q value for the ${}_{}{}^{80}{}_{}{}^{}\mathrm{Kr}$(d,p${)}^{81}$Kr reaction has been determined by extrapolating to 0.0 MeV excitation the Q values measured for nine excited states in ${}_{}{}^{81}{}_{}{}^{}\mathrm{Kr}$. (The ground state is not observed.) Peaks from the ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$(d,p${)}^{29}$Si reaction served as energy calibration points. A ground-state Q value of 5646±4 keV was found for the ${}_{}{}^{80}{}_{}{}^{}\mathrm{Kr}$(d,p${)}^{81}$Kr reaction. A ground-state mass excess for ${}_{}{}^{80}{}_{}{}^{}\mathrm{Kr}$ of -77 898±7 keV was deduced using recent ${}_{}{}^{81}{}_{}{}^{}\mathrm{Kr}$ ground-state mass measurements and the ${}_{}{}^{80}{}_{}{}^{}\mathrm{Kr}$(d,p${)}^{81}$Kr Q value from the present work.
