We have searched for proton decay via p -> mu K-+(0) using data from a 91.7 kiloton . year exposure of Super-Kamiokande- I, a 49.2 kiloton . year exposure of Super-Kamiokande II, and a 31.9 kiloton . year exposure of Super-Kamiokande III. The number of candidate events in the data was consistent with the atmospheric neutrino background expectation and no evidence for proton decay in this mode was found. We set a partial lifetime lower limit of 1.6 x 10(33) years at the 90% confidence level.
