Abstract. We report a measurement of the semimuonic decay D0 --> K- mu nu from data taken during the 1987-1988 fixed target run at Fermilab by the E687 collaboration. We obtain Gamma(D0 --> K-mu+nu)/Gamma(D0 --> K-pi+) = 0.82+-0.13+-0.13 and use this result to calculate Gamma(D0 --> K*-mu+nu)/Gamma(D0 --> K-mu+nu) = 0.59+-0.10+-0.13.
