This Letter presents a measurement of the branching fraction for the Cabibbo-suppressed decay tau/sup -/..-->..K*/sup -/(892)..nu../sub tau/ using data obtained with the Mark-II detector at SPEAR. Eleven events containing a K*/sup + -/(892) in coincidence with a muon or an electron of opposite charge were found in data which span the center-of-mass energy region 4.2..K*/sup -/(892)..nu../sub tau/)1.7=(plus-or-minus0.7)%. The absence of events at the K*/sup + -/(1430) yields a 2sigma upper limit B(tau/sup -/..-->..K*/sup -/(1430)..nu../sub tau/)<0.9%.
